Abstract

Two MX2 (M = Ni, Zn; X = Cl, Br) dimethyl N-cyanodithioiminocarbonate compounds and one CrCl2 triphenylphosphine oxide complex were isolated and elucidated by single crystal X-ray crystallography. NiCl2[(CH3S)2C═NC≡N]2 (1) features inversion-related hydrogen bonded dimers linked into chains interacting through C-H···Cl growing layers along [110] whose junction into a 3D structure is enabled by H-bonds. ZnBr2[(CH3S)2C═NC≡N]2 (2) also exhibits inversion-related H-bonded dimers. In contrast with 1, the structure of 2 comprises chains along [110], connected via C-H···Br and C-H···S into a 2D layer along [-110]. CrCl2(OPPh3)2 (3) obtaining undergone redox processes, oxidizing [CH3C(O)CH2PPh3]+ to form PPh3PO, and reducing Cr from CrVI to CrII. In the structure, each molecule is linked to height neighbors through H-bonds affording a 3D network.
二甲基氰二硫代亚胺碳酸酯和氧化三苯基膦金属卤化物配合物:分子晶体解析
用单晶X射线晶体学分离鉴定了两个MX2(M=Ni,Zn;X=Cl,Br)二甲基N-氰基二硫代亚氨基碳酸酯化合物和一个CrCl2三苯基氧化膦配合物。NiCl2[(CH3S)2C═NC lect N]2(1)的特征是通过沿[110]生长的C-H··Cl层连接成链的与反转相关的氢键二聚体,其通过氢键连接成3D结构。ZnBr2[(CH3S)2C═NC≠N]2(2)也表现出与反转相关的氢键二聚体。与1相反,2的结构包括沿[110]的链,通过C-H··Br和C-H·S连接成沿[-110]的2D层。CrCl2(OPPh3)2(3)经过氧化还原过程,氧化[CH3C(O)CH2PPh3]+形成PPh3PO,并将Cr从CrVI还原为CrII。在该结构中,每个分子通过氢键与高度相邻分子连接,形成3D网络。
