The reaction of 4-hydroxybenzoic acid (H2L),4, 4-diaminodiphenylmethane (DADPM) and Cd(NO3)2@6H2O in methane/water gave rise to a seven-coordinate Cd(Ⅱ) complex [Cd2(HL)4(H2O)6]@2H2O which has been characterized by single-crystal X-ray diffraction. The complex crystallizes in the orthorhombic system, space group Pna21 with unit cell parameters: a = 10.3352(3), b = 12.0481(3), c = 28.2016(1) ?, V = 3511.65(13) ?3, Z = 4, C28H36Cd2O20, Mr = 917.37, Dc = 1.735 g/cm3, F(000) = 1840, μ(MoKα) = 1.29mm-1. The final R and wR are 0.0536 and 0.1086 for 4898 observed reflections with I ≥ 4σ(I). The Cd(Ⅱ) is seven-coordinated in a distorted pentagonal bipyramidal geometry. The inter-molecular hydrogen bonds lead to the formation of a two-dimensional layer structure.
