摘要

在标题配合盐[Cd2(C3H7NO)2(CH5N3S)4](C6H2N3O7)4, (I)中,双核阳离子位于晶体对称中心附近。配合物阳离子的不对称单元由两个双齿硫氨基脲配体和一个与镉(II)原子配位的二甲基甲酰胺分子组成。其中一个硫氨基脲配体的S原子在倒转中心附近与镉原子桥接。配合物的正电荷由苦味酸阴离子平衡。在晶体中,阳离子通过并排的分支N-H⋯(O,O)氢键与苦克酸阴离子相连,其中中心的O原子充当两个这样的键的双受体,包围R 12(6)和R 21(6)环基序。在晶体中,进一步的N-H⋯O氢键连接各种单元,形成平行于(001)平面的板状结构,板状结构由C-H⋯O氢键连接,从而形成三维网络。

Bis(μ-thio­semicarbazide-κ3N1,S:S;κ3S:N1,S)bis­[(di­methyl­formamide-κO)(thio­semicarbazide-κ2N1,S)cadmium(II)] tetra­kis­(2,4,6-tri­nitro­phen­olate): synthesis, crystal structure and Hirshfeld surface analysis
The complete binuclear cation of the title complex salt is generated by a crystallographic center of symmetry and features bridging S atoms.
In the title complex salt, [Cd2(C3H7NO)2(CH5N3S)4](C6H2N3O7)4, (I), the binuclear cation is located about a crystallographic center of symmetry. The asymmetric unit of the complex cation is composed of two bidentate thio­semicarbazide ligands and one mol­ecule of di­methyl­formamide coordinated to a cadmium(II) atom. The S atom of one of the thio­semicarbazide ligands bridges the cadmium atoms about the inversion center. The positive charge of the complex is balanced by picrate anions. In the crystal, the cation is linked to the picrate anions by side-by-side bifurcated N—H⋯(O,O) hydrogen bonds in which the central O atom acts as a double acceptor for two such bonds, enclosing R12(6) and R21(6) ring motifs. In the crystal, further N—H⋯O hydrogen bonds link the various units to form slabs lying parallel to the (001) plane and the slabs are linked by C—H⋯O hydrogen bonds, thereby forming a three-dimensional network.

期刊介绍: Acta Crystallographica Section E: Crystallographic Communications is the IUCr''s open-access structural communications journal. It provides a fast, simple and easily accessible publication mechanism for crystal structure determinations of inorganic, metal-organic and organic compounds. The electronic submission, validation, refereeing and publication facilities of the journal ensure rapid and high-quality publication of fully validated structures. The primary article category is Research Communications; these are peer-reviewed articles describing one or more structure determinations with appropriate discussion of the science.
