摘要 合成了未见文献报道的1,10-二氧(4,7,13,16-四氮杂-18-C-6(以下用[18]N4O2代表)的硝酸镧配合物.并在丙酮中培养出{La[18]N4O2(NO3)3}*H2O配合物单晶,用X射线衍射法测定了晶体结构.晶体属三斜晶系,空间群P1-,晶胞参数a=1.0690(2) nm,b=1.3608(3) nm,c=0.8230(2) nm;α=103.10(3)°,β=104.71(3)°,γ= 84.03(3)°;Z=2,V=1.1265(4) nm3,Dc=1.779 g/cm3,μ=1.968 mm-1,F(000)=608,R=0.0307, wR=0.0566.冠醚环上的2个氧原子、4个氮原子均参与配位,3个硝酸根也均以双齿形式配位,中心La(Ⅲ)离子的配位数为12,配位多面体为畸变的二十面体,H2O分子存在于配位外界.
