摘要：

A new 3-D wheel-like calcium-cobalt phosphotungstate, Na6Ca3[Ca-2(H2O)(6)Co-9(OH)(3)(H2O)(6)(HPO4)(2)(PW9O34)(3)], is reported and characterized by IR, UV, and single-crystal X-ray diffraction. The crystal structure consists of an infinite 3-D array of [Ca-2(H2O)(6)Co-9(OH)(3)(H2O)(6)(HPO4)(2)(PW9O34)(3)](12-) anions (1) connected by sodium and calcium metal cations. The novel feature is the presence of two Ca2+, bonded to oxygen of HPO4- and to H2O spanning opposite sides in the complex anion. The stability of the crystalline product and its morphology were studied by SEM-EDX and DSC techniques.
