A low‐valent GaI complex with the superbulky b‐diketiminate ligand DIPePBDI (HC[C(Me)N‐DIPeP]2, DIPeP = 2,6‐C(H)Et2‐phenyl)) was obtained by reduction of (DIPePBDI)GaI2 (1) with KC8 in toluene. Considering that (BDI)GaI and analogue (BDI)AlI complexes are prone to decomposition and can generally only be obtained in low yields (20‐40%), the quantitative formation of (DIPePBDI)GaI (2) is remarkable and no doubt related to its excellent thermal stability even in refluxing toluene. Although the low‐valent metal center in 2 is sterically protected by the superbulky DIPePBDI ligand, it is readily oxidized by N2O to give intermediate (DIPePBDI)Ga=O which readily decomposed by abstracting a proton from the backbone Me‐substituent. Reaction with trimethylsilyl azide gave an intermediate imido complex (DIPePBDI)Ga=N(SiMe3)2 which reacted with a second equivalent of Me3SiN3 to a mixture of an azide/amido complex (DIPePBDI)GaN3[N(SiMe3)2] (4) and a tetrazagallole complex (DIPePBDI)Ga[N4(SiMe3)2] (5) in a 1:2 ratio. Whereas the azide/amido complex 4 could be structurally characterised, the tetraazagallole complex 5 was identified by NMR spectroscopy. DFT calculations on (DIPePBDI)GaI (2) and its reaction products complement this study.

The conversion of P4 with [CpBnCo(CO)2] (CpBn = C5(CH2C6H5)5) under thermal conditions gives almost exclusively the P10 complex [(CpBnCo)4(μ4‐η4:η4:η2:η2:η1:η1‐P10)]. However, its reaction with [CpBnCo]n, under mild conditions afforded a mixture of products including the P8 species [(CpBnCo)3(μ3‐η4:η2:η2:η1:η1‐P8)] and a rare Co3 cluster [(CpBnCo)2Co(μ3‐η5:η2:η1:η1‐C40H33)(μ‐H)(μ3‐H)]. The products were studied in solution by multinuclear NMR spectroscopy and mass spectrometry and, for some compounds in the solid state, by single crystal X‐ray diffraction.

Treatment of the 2‐pyridylferrocenes [CpFe(C5H3R{C5H4N})] (R= H, Me) with HAuCl4 or NaAuCl4 in aqueous acetonitrile yields the cycloaurated complexes [CpFe(C5H2R{C5H4N}AuCl2)] (R= H, 2a; Me, 2b). Reaction of 2a,b with phenylacetylene in the presence of CuI and NEt3 produces the monoalkynyl complexes [CpFe(C5H2R{C5H4N}AuI{CCPh})] (R= H, 3a; Me, 3b), while the reaction of 2a with NaCN/ LiCl yields.the bis‐cyanide [CpFe(C5H3{C5H4N}Au{CN}2)] 4a. The molecular structures of 2a, 3a, 3b and 4a were determined by X‐ray diffraction.

A series of transition metal‐pnictogenide compounds were prepared starting from [(Dipp2NacNac)MCl] (M = Cr, Mn, Fe, Zn) (Dipp2NacNac = HC{C(Me)N(Dipp)}2) and [M´E(SiMe3)2] (M´= Li, K; E = P, As, Sb) as well as [Li(Et2O)nPH2] and [Li(tmeda)AsH2]. In the course of these investigations we were able to characterize all permutations for compounds of the composition [(Dipp2NacNac)ZnE(SiMe3)2] (E = P, As, Sb) and [(Dipp2NacNac)ZnEH2] (E = P, As). Moreover, the synthesis of selected compounds of type [(Dipp2NacNac)ME(SiMe3)2] for M = Cr, Mn, Fe and E = P‐Sb are described. As part of our efforts, we established a number of bonding motifs that are underexplored in the literature to date. All isolated compounds, were examined by NMR spectroscopy, IR spectroscopy, Elemental analysis and X‐Ray structure analysis. DFT calculations on the chromium compounds were performed to investigate the binding situation between chromium and the group 15 element in more detail.
我们从[(Dipp2NacNac)MCl]（M = Cr、Mn、Fe、Zn）（Dipp2NacNac = HC{C(Me)N(Dipp)}2 ）和[M´E(SiMe3)2]（M´= Li、K；E = P、As、Sb）以及[Li(Et2O)nPH2]和[Li(tmeda)AsH2]开始，制备了一系列过渡金属锑化合物。在这些研究过程中，我们能够确定[(Dipp2NacNac)ZnE(SiMe3)2]（E = P、As、Sb）和[(Dipp2NacNac)ZnEH2]（E = P、As）组成的化合物的所有排列特征。此外，我们还介绍了 M = Cr、Mn、Fe 和 E = P-Sb 的[(Dipp2NacNac)ME(SiMe3)2] 类型化合物的合成。作为研究工作的一部分，我们建立了一些迄今为止在文献中尚未得到充分探索的成键模式。所有分离出的化合物都通过核磁共振光谱、红外光谱、元素分析和 X 射线结构分析进行了检验。对铬化合物进行了 DFT 计算，以更详细地研究铬与第 15 族元素之间的结合情况。

In this work, NH2‐containing organic ligand 5‐Aminoisophthalic acid (AIPA), and trans‐1,2‐bis(4‐pyridyl)ethene (bpe) were selected as organic ligands to construct a new two‐dimensional luminescent Zn(II) metal‐organic framework [Zn(AIPA)(bpe)1/2]·named MOF‐1. It is worth noting that MOF‐1 exhibited excellent thermal stability and chemical stability in common solvents and different pH aqueous solution. As we expected, the luminescence sensing investigations demonstrated that MOF‐1 could be deemed as a multifunctional fluorescence sensor toward Cr2O72‐ and Fe3+ via a “turn‐off” effect.Notably, MOF‐1 had high selectivity and sensitivity for Fe3+ and Cr2O72‐ with low detection limits of 9.72× 10‐5 M and 1.95× 10‐5 M, respectively. Furthermore, the possible quenching mechanisms were also explored in detail.

Omitting alloys with a compositional range we present a compilation of binary alkaline earth trielides AExTRy together with results of DFT calculations to estimate total energies and energies of formation in comparison and to analyse the distribution of charges at the atomic positions in a Bader analysis of the electron density. In a comparison of many structures, we furthermore analyse the effect of bonding on this charge distribution and reflect on the real bonding patterns in comparison with our expectations according to the Zintl concept, and we find mechanisms blocking an electron transfer as favoured by the electronegativity differences. We have subjected a variety of structural parameters together with the DFT results to a Principal Component Analysis to explore their relationship which we describe in the form of correlation matrices and biplots. The Zintl rules turn out to be a very slack guideline in rationalizing the structures of these compounds.

The reaction of Cu(OAc)2 with dimethylglyoxime (H2dmg) yields the mononuclear complex [Cu(Hdmg)2] (1), whereas the reaction of Cu(ClO4)2∙6H2O with H2dmg yields a dinuclear complex [Cu2(H2dmg)(Hdmg)(dmg)]ClO4 (2a). Systematic studies of the stoichiometric ratios of the reactants, the nature of the anion as well as pH value show that the pH value of the reaction solution/anion governs the nuclearity. I.e., basic anions and/or addition of a base yield 1. Once the product has formed in solution, it remains stable despite further changes of the pH value or addition of excess H2dmg. A conversion of one species into the other can only be achieved by simultaneous change of pH and addition of H2dmg. Accordingly, among sole addition of a base, 2a isomerizes but does not change its nuclearity. In contrast, if NaOtBu and H2dmg are added, 2a converts into 1. The same happens if the slightly basic salt Na2dmg is added to a solution of 2a. Furthermore, the formation of 2a can be exploited for the preparation of [Cu(CH3CN)4]X (X = ClO4‐, BF4‐, OTf‐) due to a recently reported cooperativity‐driven decomposition of 2a.
