2,9-Diformyl-1,10-phenanthrolinebis(2,6-dimethylanil)cobalt(Ⅱ) perchlorate was synthesized and demonstrated to be [CoL2][ClO4]2 by X-ray diffraction analysis. It crystallizes in the monoclinic system, space group C2/c with a = 22.294(4), b = 15.122(3), c = 20.640(4) (A), β =119.618(4)°, V = 6048.9(19) (A)3, C63H52Cl2CoN9O9, Mr= 1208.97, F(000) = 2504, Dc= 1.328g/cm3,Z = 4, μ = 0.436, the final R = 0.0712 and wR = 0.1718 for 1734 observed reflections (1> 2σ(Ⅰ)). In its solid state the helical polymeric chains are supramolecularly associated through intermolecular and inter- ionic hydrogen bonding interactions.
