A homochiral complex, Zn3(Hsalen)2(Py)4(H2O)2 (salen = (1R,2R)-(-)-diamino-cyclohexane-N,N’-biscarboxyl-salicylidene) 1, has been synthesized by solvothermal procedure and characterized by IR, microanalysis, TGA, powder and single-crystal X-ray crystallography. It crystallizes in monoclinic space group P2 with a = 10.9439(7), b = 10.1722(6), c = 27.3450(17), β = 97.5060(10)o, V = 3018.1(3) 3, Z = 2, Zn3(Hsalen)2(Py)4(H2O)2, Mr = 1363.33, Dc = 1.500 g/cm3, F(000) = 1408, μ = 1.257 mm-1, GOOF = 1.042, the final R = 0.0601 and wR = 0.1464 for 10322 observed reflections with I > 2σ(I). The coordination polymer 1 possesses a 1D infinite zigzag chain architecture constructed by strong hydrogen bonding interactions and the polymeric chains are further assembled into a 2D supramolecular network structure via C-H···π interactions between the cyclohexane and aromatic rings of the ligand of adjacent chains. Simultaneously, π···π stacking interactions play an important role in forming the 2D supramolecular framework.

The coordination polymer 1 possesses a 1D infinite zigzag chain architecture constructed by strong hydrogen bonding interactions and the polymeric chains are further assembled into a 2D supramolecular network structure via CH ··· π interactions between the cyclohexane and aromatic rings of the ligand of adjacent chains. Simultaneously, π ··· π stacking interactions play an important role in fo rming the 2D supramolecular framework.
