摘    要:A novel layered mixed metal vanadium-cobadt complex, (py)5Co2(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 Pca21 with a = 17.473(4), b = 11.447(2), c = 17.509(4)A^°, V = 5005.3(7)A^°3, Z = 4, Mr = 3502.1(12), Z = 4, Dc = 1.827 g/cm^3,μ(MoKα) = 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 〉 2σ(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).

Abstract:A novel layered mixed metal vanadium-cobadt complex,(py) _5Co_2(H_2O)_3[V_4O_(12)] 1(py=pyridine),was hydro(solvo)thermally synthesized and characterized by single-crystal X-ray diffraction. It crystallizes in orthorhombic,space group Pca2_1 withα=17.473(4)(A),b=11.447(2),c= 17.509(4)(A),V=5005.3(7)(A)~3,Z=4,Mr=3502.1(12),Z=4,Dc=1.827 g/cm~3,μ(MoKα)=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> 2σ(Ⅰ) and 460 variables. Complex 1 consists of tetrahedral VO_4groups to form the large layers which are alternately bonded by two cobalt complex species Co(py)_2(H_2O)_2and Co(py)_3(H_2O).
