A novel layered mixed metal vanadium-cobadt complex, (py)(5)Co-2(H2O)(3)[V4O12] 1 (py = pyridine), was hydro(solvo)thermally synthesized and characterized by single-crystal X-ray diffraction. It crystallizes in orthorhombic, space group Pca2(1) with a = 17.473(4), b = 11.447(2), c = 17.509(4) angstrom, V = 5005.3(7) angstrom(3), Z = 4, M-r = 3502.1(12), Z = 4, D-c = 1.827 g/cm(3), mu(MoK alpha) = 2.023 mm(-1), F(000) = 1928, S = 1.020, the final R = 0.0400 and wR = 0.1063 for 6035 observed reflections with I > 2 sigma(I) and 460 variables. Complex 1 consists of tetrahedral VO4 groups to form the large layers which are alternately bonded by two cobalt complex Species Co(py)(2)(H2O)(2) and Co(py)(3)(H2O).
