Crystal structure of aqua­tris­{μ-N-[bis(diethyl­amino)phosphoryl]-2,2,2-tri­chloroacetamidato-κ3 O,O′:O}calciumsodium

In the mol-ecular structure of the title compound, [CaNa(C10H20Cl3N3O2P)3(H2O)], the Ca2+ ion has a slightly distorted octa-hedral 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 mol-ecule. 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 mol-ecules and the phosphoryl groups.
