Abstract

The structure of the title manganese complex, [Mn(C(5)H(9)OS(2))(2)(C(5)H(5)N)(2)] or [Mn(S(2)CO-n-Bu)(2)(C(5)H(5)N)(2)], consists of discrete monomeric entities with Mn(2+) ions located on centres of inversion. The metal atom is coordinated by a six-coordinate trans-N(2)S(4) donor set with the pyridyl N atoms located in the apical positions. The observed slight deviations from octa-hedral geometry are caused by the bite angle of the bidentate κ(2)-S(2)CO-n-Bu ligands [69.48 (1)°]. The O(CH(2))(3)(CH(3)) chains of the O-n-butyl dithio-carbonate units are disordered over two sets of sites with an occupancy ratio of 0.589 (2):0.411 (2).

摘要

标题锰配合物[Mn(C₅H₉OS₂)₂(C₅H₅N)₂]或[Mn(S₂CO-n-Bu)₂(C₅H₅N)₂]的结构由离散的单体实体组成,其中Mn(2+)离子位于对称中心。金属原子由一个六配位的反式-N₂S₄供体基团配位,吡啶基N原子位于顶端位置。观察到与八面体几何形状的轻微偏差是由双齿κ(2)-S₂CO-n-Bu配体的咬角[69.48 (1)°]引起的。正丁基二硫代碳酸酯单元的O(CH₂)₃(CH₃)链在两组位置上无序,占有率为0.589 (2):0.411 (2)。
