At room temperature, the reaction of CdNO32@4H2O and anisic acid in an ethanol solution affords the cadmium (Ⅱ) complex [Cd(H2O)(CH3OC6H4COO)2]n. The crystal is of monoclinic, empirical formula C16H16O7Cd, Mr = 432.69, space group C2/c with parameters: a = 34.211(2), b = 6.030(2), c = 7.611(3)A, β = 95.619(5)°, V = 1562.5(9)A3, Z = 4, Dc = 1.831 g/cm3, μ = 1.434 mm-1, F000 = 856, R = 0.0215 and wR = 0.0456. 1121 reflections with I>2σ(I) were considered to be observed. Each cadmium atom is seven-coordinate in a distorted pentagonal bipyramidal geometry. The Cd (Ⅱ) center is doubly bridged with the neighboring Cd centers by anisate ligands to form a four-membered ring with a repeating unit of Cd-O-Cd-O-. The extended structure and hydrogen-bonding patterns displayed in the complex were studied.
