Abstract

The bis-chelated mononuclear nickel(II) complex shows inversion symmetry, with the dithiocarbazato ligand in the usual trans configuration and the central metal cation in a square-planar coordination environment.

The central Ni^II atom in the title complex, [Ni(C₁₃H₂₅N₂S₂)₂], is located on an inversion center and adopts a roughly square-planar coordination environment defined by two chelating N,S donor sets of two symmetry-related ligands in a trans configuration. The Ni—N and Ni—S bond lenghts are 1.9193 (14) and 2.1788 (5) Å, respectively, with a chelating N—Ni—S bond angle of 86.05 (4)°. These data are compared with those measured for similar dithiocarbazato ligands that bear n-octyl or n-hexyl alkyl chains. Slight differences are observed with respect to the phenylethylidene derivative where the ligands are bound cis relative to one another.

双[S-辛基 3-(2-甲基亚丙基)二硫代卡巴唑-κ2 N 3 S]镍(II)

标题复合物[Ni(C13H25N2S2)2]中的中心 NiII 原子位于一个反转中心上，并采用了由两个对称相关配体的两个螯合 N、S 供体组以反式构型定义的大致正方形平面配位环境。Ni-N 和 Ni-S 键长分别为 1.9193 (14) Å 和 2.1788 (5) Å，螯合 N-Ni-S 键角为 86.05 (4)°。这些数据与带有正辛基或正己基烷基链的类似二硫代咔唑配体的数据进行了比较。与苯基亚乙基衍生物相比，配体之间的顺式结合略有不同。
