Abstract Selective oxidation of benzene to phenol is done in the liquid phase over copper-substituted LaFeO3 perovskite oxides as catalyst using H2O2 as oxidant under mild reaction conditions. Among the different copper-substituted perovskite catalysts synthesized by a novel solution combustion method, the LaFe0.90Cu0.10O3 catalyst showed highest activity (∼56 % with 100 % selectivity of phenol) and also gives better activity than the corresponding catalyst made via incipient wetness impregnation of 10 at % Cu over combustion-synthesized LaFeO3. XRD analysis revealed formation of the perovskite phase as the predominant one. The greater activity of the combustion-made catalyst has been attributed to the occurrence of a peculiar poorly-defined structure having substitutional copper ion sites on top of the LaFeO3 particle as observed in HRTEM analysis. Much less occurrence of this phase in the impregnated catalyst, where copper is primarily present as dispersed CuO crystallites, explains its comparatively lower activity in the oxidation reaction. The effect of catalyst recycling shows negligible change of activity for the combustion-made catalyst whereas the analogous impregnated catalyst shows considerable decrease in activity in recycling. This explained to be due to the essentially intact poorly-defined structure in the former and leaching of the finely dispersed CuO crystallites from the latter catalyst during cycling.

Abstract By utilizing the well-known selective xanthine oxidase inhibitor topiroxostat, a new zinc(II) complex Zn(L)2(H2O)2 (1) [HL = 4-(3-(pyridine-4-yl)-1H-1,2,4-triazol-5-yl)picolinic acid] has been hydrothermally synthesized, involving in-situ ligand formation upon hydrolysis of topiroxostat. The complex has been structurally characterized by elemental analysis, IR spectroscopy, thermogravimetric analysis, powder X-ray diffraction, and single-crystal X-ray diffraction. X-ray structural analysis revealed that complex 1 is a N,O-chelating mononuclear Zn(II) complex. Complex 1 shows good thermal stability and exhibits photoluminescence in the solid state at room temperature. Moreover, complex 1 has been shown to be effective in the solvent-free ring-opening polymerization of ε-caprolactone without any co-catalyst or initiator.

Abstract A metal-organic framework (MOF) {[Cd(EtOIPA)(bpp)(H2O)]·2H2O} n (1) has been synthesized under basic hydrothermal conditions by using of 5-ethoxyisophthalic acid (EtOIPAH2) and 1,3-bis(4-pyridyl)propane (bpp) as reagents for cadmium nitrate. Compound 1 was characterized by elemental analysis, single-crystal X-ray diffraction and UV/Vis spectroscopy. In 1, the bpp ligands extend the EtOIPA-Cd chains along the ab plane to form a 2-fold 3D interpenetrating network. Compound 1 emits blue phosphorescence at room temperature with a long lifetime of 4.2 ms.

Abstract The solid solutions LaNiIn1–xSn x and CeNiIn1–xSn x were studied by means of X-ray powder diffraction and EDX analyses in the full concentration range for samples annealed at T = 870 K. The limited solubility of the fourth component in the starting compounds with equiatomic composition, and the limits and the unit cell parameters of the solid solutions have been determined. The crystal structure of CeNiIn0.57Sn0.43 was refined from single-crystal X-ray diffraction data: ZrNiAl-type structure; hexagonal space group P 6 ‾ $overline{6}$ 2m, a = 0.74213(10), c = 0.40825(8) nm, R1 = 0.0155, wR2 = 0.0303, 282 independent hkl reflections and 15 refined parameters. The existence ranges within the solid solutions are discussed.

Abstract The N-heterocyclic stannylene [Fe{(η5-C5H4)NC6H3-2,6-iPr2}2Sn] (1) has been synthesised from SnCl2 and the lithium amide [Fe{(η5-C5H4)NC6H3-2,6-iPr2}2Li2]. Compound 1 is inert towards H2, CO, CO2, and MeI under ambient conditions. Immediate hydrolysis and ammonolysis was observed with H2O and NH3, respectively. While oxidation reactions of 1 with chalcogens (O2, S8, Se8) afforded only intractable material, the reaction with Ph2Se2 cleanly furnished [Fe{(η5-C5H4)NC6H3-2,6-iPr2}2Sn(SePh)2] (2). Compounds 1 and 2 have been structurally characterised by single-crystal X-ray diffraction. Compound 2 exhibits an intramolecular CH⋯Se contact compatible with a weak hydrogen bond.

Abstract The ternary silicide ErNi4.04Si0.96 was synthesized by arc-melting of stoichiometric quantities of the elements, and its crystal structure has been determined using single-crystal X-ray diffraction data. The compound crystallizes in the CaCu5 structure type: hexagonal space group P6/mmm, Pearson code hP6, Z = 1; a = 4.874(3), c = 3.959(2) Å, V = 81.5(1) Å3; R1 = 0.0239, wR2 = 0.0503, for 67 independent reflections with I > 2σ(I) and eight variables. The erbium and nickel atoms occupy the crystallographic positions 1a and 2c, respectively. The position 3g is occupied by a mixture of Ni and Si atoms. The structure of this silicide represents a packing of bipyramidal units built from nickel and Ni/Si atoms.

Abstract Metathesis reactions designed to produce nominally the pseudo-ternary ATl[N(CN)2]2 compounds (A = Li, Na, K, Rb or Cs) either yielded solid solutions or separated pseudo-binary dicyanamides next to the new compounds LiTl[N(CN)2]2 and Tl0.89(1)Cs0.11(1)[N(CN)2]. Tetragonal LiTl[N(CN)2]2 (a = 724.96(2), c = 1411.77(6) pm, Z = 4) is crystallizing isotypically with LiK[N(CN)2]2 in the space group I4/mcm, while orthorhombic Tl0.89(1)Cs0.11(1)[N(CN)2] (a = 858.19(4), b = 654.22(2), c = 738.94(4) pm, Z = 4) adopts the α-K[N(CN)2]-type structure in the space group Pbcm, which Tl[N(CN)2] itself also assumes, with the unique cationic position shared by Tl+ and Cs+ in an approximate 9:1 molar ratio. The Raman spectra of the new compounds are presented and compared to those of Tl[N(CN)2], LiK[N(CN)2]2 and LiRb[N(CN)2]2.
