| Abstract: The title complex Co(NTB)Cl·3[(CH3)2SO]was synthesised by tris(2-benzimidazylmethyl) amine(NTB) and cobalt chloride in dimethyl sulfoxide. The crystals are triclinic, space group P-1(No.2) with a=0.9679(3),b=1.1780(5),c=1.6102(9)nm,α =71.07(8),β =89.27(8),γ =84.81(3)°,V=1.729(2)nm3,Z=2,Dc=1.408g· cm-3,Mr=733.24,F(000)=762,μ =0.7864cm-1. The structural solution and refinement based on 1825 independence reflections (I≥3σ(I)) are converged to R=0.065, Rw=0.072. The center cobalt(Ⅱ) ion is coordinated with four nitrogen atoms from the NTB and a chlorion to form a light distorted trigonal bipyramid configuration, where the cobalt? sets in the centre of the configuration. |
