摘要
Y(TTA)_2(TPPO)_2NO_3(TTA:噻吩甲酰三氟丙酮根,TPPO:三苯基氧化膦)配合物的晶体结构测定结果表明它属于三斜晶系,空间群P1.晶胞参数:a=1.1783(5)nm,b=1.2503(4)nm,c=1.1079(5)nm,α=102.07(3)°,β=117.92(3)°,γ=102.63(3)°,V=1.3122nm^3,Z=1.ρ=1.46g·cm^(-3).最终计算R,R_W分别为0.054和0.063.钇(Ⅲ)离子与8个氧原子配位,其中硝酸根为双齿配位.平均Y-O键长是0.235nm.
The crystal structuer of Y(TTA)_2(TPPO)_2NO_3(TTA:thenoyltrifluoro- acetonato,TPPO:triphenylphosphine oxide)complex shows that it crystallizes in the triclinic,space group P1 with one molecule in the unit cell.The crystallographic data are a=1.1783(5)nm,b=1.2503(4)nm,c=1.1079(5)nm,α=102.07(3)°, β=117.92(3)°,γ=102.63(3)°,V=1.3122nm^3,Z=1.ρ=1.46g·cm^(-3).The final calculated R, R,are 0.054 and 0.063 respectively.The yttrium (Ⅲ)ion is coordinated to eight oxygen atoms.The average Y-O bond length is 0.235nm.
