采用水热法合成出一种含一价铜配合物的新型双金属钼氧簇合物[5-(4-Br-Ph)-2,4′-Hbpy]2[Cu(5-(4-Br-Ph)-2,4′-bpy)2]2[Mo8O26],并通过X射线单晶结构分析、红外光谱分析、元素分析以及X射线粉末衍射分析对该化合物的结构进行了表征.结果表明,该化合物属单斜晶系,P21/c空间群,晶胞参数a=1.4411(3)nm,b=1.3924(3)nm,c=2.5183(5)nm,β=99.06(3)°,V=4.990(17)nm3,Z=2;该化合物是由一价铜配合物{Cu(5-(4-Br-Ph)-2,4′-bpy)2}+与{β-Mo8O26}4-簇通过共价配位键连接形成的新型多金属钼酸盐,其中游离的质子化配体作为抗衡阳离子.
A novel bimetallic molybdenum oxygen cluster [5- (4-Br-Ph) -2,4’-Hbpy] 2 [Cu (5- Br-Ph) -2,4’-bpy) 2] 2 [Mo8O26] was prepared and its structure was characterized by X-ray single crystal structure analysis, infrared spectrum analysis, elemental analysis and X-ray powder diffraction analysis. The results show that the compound belongs to the monoclinic space group P21 / c with cell parameters of a = 1.4411 (3) nm, b = 1.3924 (3) nm, c = 2.5183 , V = 4.990 (17) nm3, and Z = 2. The compound was synthesized from {Cu (5- (4-Br-Ph) -2,4’-bpy) 2} and {β-Mo8O26 } 4-Cluster A new type of polymetallic molybdate formed by the covalent coordination bond, with the free protonated ligand acting as a counter cation.
