摘    要:标题化合物Ni(tacn)2]2·Co(dmg)2Cl2]4·4H2O(C56H112Cl8Co4N28Ni2O20)是由NiCl2·6H2O、CoCl2·6H2O、tacn·3HCl和dmg(丁二酮肟)在甲醇溶液中反应而得。结构通过经石墨单色器单色化的MoKα射线(λ=0.71073A)衍射法测定,共收集到16173个衍射点,其中独立衍射点14816个。解析结果表明,晶体属于三斜晶系,空间群为P1,晶胞参数为a=14.771(4),b=18.297(5),c=19.214(5)A,α=118.035(4),β=97.545(5),γ=91.273(5)°,V=4523(2)A3,Z=2。Mr=2102.48,Dc=1.544g/cm3,μ(MoKα)=1.435mm-1,F(000)=2176。晶体用直接法解出,经过最小二乘法对原子参数进行修正,最终的偏离因子为R=0.0884,wR=0.2239。分子中Ni(tacn)2]2+阳离子和Co(dmg)2Cl2]-阴离子间是通过静电才互作用结合在一起的。

关 键 词:大环配体  双金属配合物  晶体结构
