Crystal structure of aquatris{μ-N-[bis(diethylamino)phosphoryl]-2,2,2-trichloroacetamidato-κ3O,O′:O}calciumsodium

Abstract

In the molecular structure of the title compound, [CaNa(C10H20Cl3N3O2P)3(H2O)], the Ca2+ ion has a slightly distorted octahedral coordination environment defined by six O atoms which belong to the carbonyl and phosphoryl groups of the three coordinating ligands. Two Cl atoms of CCl3 groups and four O atoms form the coordination environment of the Na+ ion: three from the carbonyl groups of ligands and one O atom from a coordinating water molecule. In the crystal, the bimetallic complexes are assembled into chains along the c-axis direction via O—H...O hydrogen bonds that involve the coordinating water molecules and the phosphoryl groups.
