A homochrial manganese(Ⅱ) complex derived from chiral salen ligand (1R,2R)-(-)diaminocyclohexane-N,N-biscarboxyl-salicylidene) (1) has been synthesized through solvothermal procedure and characterized by IR,elemental analysis,TGA,circular dichroism (CD),powder and single-crystal X-ray crystallography.It crystallizes in monoclinic,space group C2 with a=32.987(7),b=7.4662(15),c=17.931(4),β=97.82(3)°,V=4375.0(15) 3,Z=8,D c=1.544 g/cm 3,F(000)=2096,M r=508.36,μ=0.658 mm-1,the final GOOF=0.975,R=0.0676 and wR=0.2068 for 6357 observed reflections with I > 2σ(Ⅰ).The coordination polymer 1 possesses a 1D infinite zigzag chain architecture constructed by the dicarboxyl-functionalized metallosalen ligand (MnSalen),and the polymeric chains are further assembled into a 2D supramolecular network structure via strong intermolecular hydrogen bonding interactions between the adjacent zigzag chains.
