Abstract
The asymmetric unit of the title compound, [ErCl3(C10H17Cl3N3O2P)(3)], contains two independent molecules. In each molecule, the Er-III ion is six-coordinated in a slightly distorted octahedral ErO3Cl3 geometry with a fac-arrangement of the donor atoms. Intramolecular N-H center dot center dot center dot Cl hydrogen bonds influence the molecular conformations. Some of the pyrrolidine fragments in the N-[bis(pyrrolidin-1-yl)phosphoryl]-2,2,2-trichloroacetamide ligands are disordered over two conformations of equal occupancy. The unusually porous crystal packing exhibits voids of 162, 158 and 13 angstrom(3) and short intermolecular Cl center dot center dot center dot O contacts of 2.876 (3) and 3.022 (4) angstrom.This publication has 6 references indexed in Scilit:
