摘要：

At room temperature, the reaction of Cd(NO3)(2).4H(2)O 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, M-r = 432.69, space group C2/c with parameters: a = 34.211(2), b = 6.030(2), c = 7.61](3) Angstrom,beta = 95.619(5)degrees, V= 1562.5(9) Angstrom(3), Z = 4, D-c = 1.831 g/cm(3), mu = 1.434 mm(-1), F(000) 856, R = 0.0215 and wR = 0.0456. 1121 reflections with I greater than or equal to 2sigma(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.
