摘要
At room temperature, the reaction of Cd(NO3)24H2O 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) ? = 95.619(5)? V = 1562.5(9) ?, Z = 4, Dc = 1.831 g/cm3, = 1.434 mm-1, F(000) = 856, R = 0.0215 and wR = 0.0456. 1121 reflections with I ≥ 2s(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 CdOCdO-. The extended structure and hydrogen-bonding patterns displayed in the complex were studied.
