Polynuclear Lanthanoid Complexes Containing Aluminium—The Structure ofHoAl(CF_3COO)_2(CF_3CHOO)(C_2H_5)_2(C_4H_8O)_2_2 at 233K

摘要

[HoAl（CF3COO）2（CF3CHOO）（C2H5）2（C4H8O）2]2,Mr=1468.7,monoclinic,P 21/n,a=1.0084（4）,b=1.8453（6）,c=1.4501（6）nm,β=102.40（3）°,V=2.6355（1）nm3,Z=2,Dc=1.81gcm-3,F（000）=1511,T=233K,Mo Kα radiation（λ=0.071069nm）.R=0.052 for 6176 unique reflections[Ⅰ≥36（Ⅰ）].The structuralunits consist of dimeric molecules with the mixed ligand and central bimetallic atoms,which are polynuclearlanthanoid complexes containing aluminium.Ho-Ho’distance is 0.3619（1）nm.The coordination polyhedron ofHo can be described in terms of a distored bicap-prism.
