The crystal structure of the title compound, C14H12N2O2S, reveals two symmetrically independent mol-ecules within the asymmetric unit. Each mol-ecule contains a chromenone core attached to a 2-thio-phene ring, cyano, and amino groups. The 2-thio-phene ring of one of the two mol-ecules in the asymmetric unit was found to be disordered over two positions, with the major component having a site occupancy factor of 0.837 (2). The 2-thio-phene ring is nearly orthogonal to the fused 4H-pyran ring, with dihedral angles between the two sets of planes being 89.5 (5) and 89.63 (8)°. Inter-molecular hydrogen bonding, involving N-H⋯N and N-H⋯O inter-actions, creates two distinct motifs leading to the formation of a two-dimensional supra-molecular network along the crystallographic ac plane.

The crystal structure of 1,4-bis-(neopent-yloxy)pillar[5]arene, C95H140N2O10 (TbuP), featuring two encapsulated pyridine mol-ecules, reveals significant host-guest inter-actions. Inter-estingly, the pyridine guests are positioned near the neopent-yloxy substituents instead of the electron-rich aromatic core of the pillar[5]arene. This spatial arrangement suggests a preference for the pyridine mol-ecules to engage with the aliphatic regions of the host. Detailed analysis of the structural characteristics of this host-guest system (TbuP·2Py), as well as its packing pattern within the crystal network, is presented and discussed.

The title compound, C18H12Cl3O4P, is the symmetric phosphate derived from para-chloro-phenol and phospho-ric acid. Two of the three aromatic moieties adopt syn-orientation towards the P=O bond while the last chloro-phenol ring is pointing away from this bond. In the extended structure, C-H⋯O bonds connect the individual mol-ecules into sheets lying perpendicular to the crystallographic b axis.

标题化合物 C18H12Cl3O4P 是对氯苯酚和磷酸的对称磷酸酯。三个芳香分子中有两个朝向 P=O 键,而最后一个氯酚环则远离该键。在扩展结构中,C-H⋯O 键将各个分子单元连接成垂直于晶体学 b 轴的薄片。

The title dinuclear and centrosymmetric complex mol­ecule exhibits a highly distorted octa­hedral O4N2 coordination set about the central zinc(II) atom.
The title compound, [Zn2(C6H8O4)2(C10H9N3)2]·3H2O or {Zn2[(C5H4N)2NH]2[μ-(CH2)4(COO)2]2}·3H2O, was separ­ated from the solvothermal reaction of zinc(II) sulfate hepta­hydrate, 2,2′-di­pyridyl­amine and sodium adipate. The dinuclear metal complex has a centrosymmetric structure, with the ZnII atom adopting a highly distorted octa­hedral coordination sphere composed of four oxygen atoms from bridging adipato ligands and two pyridine nitro­gen atoms. In the crystal, the title compound aggregates into a tri-periodic supra­molecular structure through inter­molecular hydrogen-bonding networks of the form O—H⋯O and N—H⋯O.

Ti4Fe2C0.82O0.18 is the first example where C and O atoms co-occupy the same site in filled Ti2Fe structures.
The phase with composition Ti4Fe2C0.82O0.18, tetra­titanium diiron carbide oxide, was unexpectedly synthesized by high-pressure sinter­ing (HPS) of a stoichiometric mixture with nominal composition Ti2Fe. The Ti4Fe2C0.82O0.18 phase crystallizes in the Fd
m space group and can be considered as the Ti2Fe structure filled with C and O atoms co-occupying the same octa­hedral void [occupancy ratio 0.82 (7):0.18 (7)]. The Ti4Fe2C0.82O0.18 phase is isotypic with Ti4Ni2C and Ti4Fe2O0.407, and is the first example where C and O atoms co-occupy the same site in filled Ti2Fe structures.

通过高压烧结(HPS)标称成分为 Ti2Fe 的化学计量混合物,意外合成了成分为 Ti4Fe2C0.82O0.18 的四钛二铁碳化物相。Ti4Fe2C0.82O0.18 相在 Fd m 空间群中结晶,可视为填充了 C 原子和 O 原子的 Ti2Fe 结构,它们共同占据同一个八面体空隙[占据比为 0.82 (7):0.18 (7)]。Ti4Fe2C0.82O0.18 相与 Ti4Ni2C 和 Ti4Fe2O0.407 同型,是填充 Ti2Fe 结构中 C 原子和 O 原子共占同一位点的第一个实例。
