摘要

该化合物[Zn2(C16H14N2S2)2]2·0.18C2H6OS·0.82CH3OH晶体结构中的不对称单元由两个有序的双μ-2,2'-[(丁烷-2,3-二烷基二烷基)双(氮杂基二烷基)]二苯乙硫代二锌(II)分子和在同一位置的无序溶剂组合组成，其精化为18.1(7)%二甲亚砜和81.9(7)%甲醇。该化合物具有金属团簇结构，由两个锌(II)配合物分子连接在一起，形成菱形的Zn2S2排列。该复合物先前根据非结构证据被认为是单体[Jadamus, Fernando & Freiser(1964)]。j。化学。[j].生物工程学报，2016,33(2):444 - 444。每个Zn(II)原子是五配位的，并表现出扭曲的三角双锥体几何形状。这种结构可能对锌-硫酸盐键、席夫碱的配位化学和蛋白质的折叠有兴趣。该结构表现出弱的分子间C-H··S、C-H··O和C-H··N相互作用，并在Zn2S2菱形周围含有独特的配体键排列。

Bis{μ-2,2'-[(butane-2,3-diylidene)bis(azanylylidene)]dibenzenethiolato}dizinc(II)-dimethyl sulfoxide-methanol (2/0.18/0.82).

The asymmetric unit in the crystal structure of the title compound, [Zn2(C16H14N2S2)2]2·0.18C2H6OS·0.82CH3OH, consists of two ordered bis{μ-2,2'-[(butane-2,3-diylidene)bis(azanylylidene)]dibenzenethiolato}dizinc(II) molecules and a disordered solvent combination at the same location which refined to 18.1 (7)% dimethyl sulfoxide and 81.9 (7)% methanol. The compound has a metallic cluster structure formed by the joining together of two zinc(II) complex molecules, forming a rhomboidal Zn2S2 arrangement. This complex was previously suggested on the basis of nonstructural evidence to be a monomer [Jadamus, Fernando & Freiser (1964). J. Am. Chem. Soc. 86, 3056-3059]. Each Zn(II) atom is five-coordinated and exhibits distorted trigonal bipyramidal geometry. The structure may be of interest with respect to zinc-thiolate bonds, the coordination chemistry of Schiff bases and the folding of proteins. The structure displays weak intermolecular C-H···S, C-H···O and C-H···N interactions, and contains a unique bonding arrangement of the ligands around the Zn2S2 rhomboid.

期刊介绍： Acta Crystallographica Section C: Structural Chemistry is continuing its transition to a journal that publishes exciting science with structural content, in particular, important results relating to the chemical sciences. Section C is the journal of choice for the rapid publication of articles that highlight interesting research facilitated by the determination, calculation or analysis of structures of any type, other than macromolecular structures. Articles that emphasize the science and the outcomes that were enabled by the study are particularly welcomed. Authors are encouraged to include mainstream science in their papers, thereby producing manuscripts that are substantial scientific well-rounded contributions that appeal to a broad community of readers and increase the profile of the authors.
