摘要
合成了配合物Cu(phen) 2 (dca) 2 (phen =C12 H8N2 为 1,10 -邻菲啉 ,dca-为二氰基氨基阴离子 ) ,用IR对其结构进行了初步表征 ,并测定了配合物的晶体结构。该晶体属单斜晶系 ,空间群为P2 1/c ;晶胞参数a =0 .886 9( 2 )nm ,b =1.4 6 91( 2 )nm ,c =1.92 98( 2 )nm ,β =10 0 .90 ( 1)° ;V =2 .4 6 91( 8)nm3 ,Z =4 ,F( 0 0 0 ) =1132 .0 0 ,Dc =1.4 96g/cm3 ,R =0 .0 5 1,RW=0 .0 6 8。中心铜 (Ⅱ )离子分别与两个phen中的四个N原子和两个dca-的两个N原子配位 ,形成六配位的变形八面体结构。
The complex Cu(phen) 2 (dca) 2 was synthesized. Its structure was characterized by IR spectra and X-ray diffraction. The crystal belongs to monoclinic system and space group P2 1/c with parameters: a=0.8869(2)nm, b=1.4691(2)nm,c=1.9298(2)nm,β=100.90(1)°;V= 2.4691(8)nm 3, Z=4,F(000)=1132.00,Dc=1.496g/cm 3,R=0.051,R W=0.068.The copper(Ⅱ) ion lies in a elongated tetragonal bipyramidal (4+2) coordination geometry composed of four nitrogen atoms of two 1,10-phenanthroline ligands and two nitrogen atoms of two dicyanamide ligands.
