摘要
利用溶剂热法合成了一个新的钴(II)配合物[Co(pht)2(MeOH)2(H2O)2](Hpht:苯妥英,即5,5-二苯基-2,2咪唑烷酮),通过元素分析、红外光谱、热重差热分析、X射线单晶衍射等技术对其结构进行了表征。单晶结构分析表明,该晶体属单斜晶系,P21/C空间群,晶胞参数:a=1.2124(2)nm,b=1.09996(19)nm,c=1.1574(2)nm,β=92.555(2)°,V=1.5419(5)nm3,Dc=1.425 mg/m3,Z=2,F(000)=690,μ=0.615 mm-1,R1=0.0467,wR2=0.1116[I>2σ(I)],GOF=1.026。Co(II)离子位于八面体的中心,与六个配位原子配位(4O+2N)。
The title complex [ Co ( pht)2 ( MeOH)2 (H2O)2 ] ( Hpht = 5,5-diphenylhydantoin, i. e. phenytoin) has been solvothermally synthesized and characterized by means of elemental analysis, IR , TG-DTA and single-crystal X-ray diffraction. The crystal of Co(II) complex belongs to monoclinic system with space group P21/C,a = 1. 2124 (2) nm,b = 1. 09996 (19) nm,c = 1. 1574 (2) nm,β =92. 555 (2) °, V = 1. 5419(5 ) nm^3 ,Dc = 1. 425 mg/m^3 ,Z = 2, F(000) = 690 ,μ =0.615mm^-1 ,R1 =0.0467 ,wR2 =0. 1116 [I 〉2σ(1) ] ,GOF = 1. 026. The Co(II) atom is located at the center of a octahedron of six coordinating atoms (four O atoms and two N atoms).
