摘要
合成了新化合物(N_2H_6)_(0.5)[(CH_3)_4N]{[MoO(H_2O)C_2O_4]_2(μ_2-O)_2}·H_2O,并运用元素分析、红外和单晶X衍射对其结构进行了表征.测定结果证实该化合物有两个共边连接的钼氧八面体,钼原子都是正五价,且有Mo—Mo键存在,每个钼上有一个螫合配位的草酸根.该化合物属单斜晶系P2_1/c,a=0.6059(1)nm,b=1.6658(3)nm,c=1.8249(4)nm,β=94.02(3)°,V=1.8374(6)nm^3,R_1=0.0337,wR_2=0.0908.
A new compound (N2H6)0.5[(CH3)4N] { [MoO(H2O)C2O4]2(μ2 - O)2}·H2O was prepared and its structure was determined by X- ray diffraction analysis. The compound has two edge - shared molybdenum - oxygen octahedra and all the Mo atoms are of charge + 5. Mo centers are chelated by oxalates. The crystal is monoclinic, space group P21/c, a = 0.6059( 1 )nm, b = 1.6658(3)nm, c = 1.8249(4)nm,β = 94.02(3)°, V =1.8374(6)nm3, R1=0.0337, wR2 = 0.0908.
