摘要 报道标题化合物La(PMBP)_3(H_2O)_2,Hpmbp=C_(17)H_(14)N_2O_2的合成及晶体结构,晶体属于单斜晶系,空间群C2/c,晶体学数据:a=24.744(5),b=16.325(6),c=25.871(5),β=105.44(3)°,V=10073(2)3,M_r=1006,Z=8,D_x=1.328g/cm^(-3),μ=9.042cm^(-1),F(000)=4094。最终偏离因子R=0.049,R_w=0.059。分子中La(Ⅲ)与8个氧原子配位形成三角十二面体构型,La-O平均键长为2.496(2)。 The title compound was synthesized and its crystal structure was determined by X-raydiffraction method. The crystallographic data are as follows:space group C2/c,a= 24. 744 (5) .b=16. 32d(6).c=25.871 (5), β= 105. 44(3)°, V= 10073(2)3,Z=8, M_r= 1006. 86,D_x=1. 328 g/cm ̄(-3).μ= 9. 042 cm ̄(-1) , F(000) =4096, R=0. 049.R_w=0. 059.The structure analysis shows that the structure belongs to dodecahedral configuration. Inthe dodecahedral configuration, La( Ⅲ ) is located at the centre and coordinated to eight oxygenatoms.the average La-O bond length is 2. 496(2).
