A new complex [Mn(L)(NCS)]2·0.5CH3CN (H2L = N,N’-bis(chlorosalicylidene)-1,2-diaminoethane) has been synthesized,and its structure (C70H51Cl8Mn4N13O8S4,Mr = 1833.84) was determined by single-crystal X-ray diffraction analysis. The crystal belongs to the monoclinic system,space group C2/c with a = 25.883(2),b = 12.3320(13),c = 13.5951(16) ,β = 112.906(2),V = 3997.2(7) 3,Z = 2,Dc = 1.524 g/cm3,μ(MoKα) = 1.050mm-1,F(000) = 1852,S = 1.098,the final R = 0.0630 and wR = 0.1847 for 2542 reflections with Ⅰ > 2σ(Ⅰ). The centrosymmetric title complex contains a dimer in which two distorted octahedral Mn(Ⅲ) centers are bridged equatorially by phenolic oxygen of the Schiff base ligand. The units of the complex are linked via weak C-H···N hydrogen bonds,leading to the formation of 1D chains along the b axis. The weak π-π packing interactions and weak intermolecular C(3)-H(3)···N(3) hydrogen bonds stabilize the crystal structure.
