用Nicolet R 3M/E四圆衍射仪,测得了GdCl_3(DME)·2THF的晶体结构(DME=Dimethoxyethane)。晶体属于单斜晶系,空间点群是P2_1/a,Z=4。晶格参数a=13.507(4),b=8.553(2),c=15.951(4)(?),β=90.65(2)°。 晶体结构应用Patterson和Fourier技术,并经块矩阵最小二乘法解出最后的一致性因子R=0.049。钆离子同三个氯原子,两个四氢呋喃中的氧原子及(DME)中的两个氧原子键合,形成七配位的配合物。Gd—Cl和Gd—O的距离分别在2.626～2.650(?)和2.443～2.482(?)范围内。
The crystal structure of GdCl_3 (DME) · 2THF (DME = Dimethoxyethane) was measured using a Nicolet R 3M / E four-circle diffractometer. The crystal belongs to the monoclinic system, the space point group is P2_1 / a, Z = 4. The lattice parameters a = 13.507 (4), b = 8.553 (2), c = 15.951 (4) (?), Β = 90.65 (2) °. The Patterson and Fourier techniques were applied to the crystal structure, and the final concordance factor R = 0.049 was solved by the least square method of block matrix. Gadolinium ions combine with three chlorine atoms, two oxygen atoms in two tetrahydrofuran and two oxygen atoms in (DME) to form a seven-coordinated complex. The distances between Gd-Cl and Gd-O ranged from 2.626 to 2.650 (?) And from 2.443 to 2.482 (?), Respectively.
