Crystal structure of aqua-tris-{μ-N-[bis(diethyl-amino)phosphoryl]-2,2,2-tri-chloroacetamidato-κ(3)O,O':O}calciumsodium.

In the mol-ecular structure of the title compound, [CaNa(C(10)H(20)Cl(3)N(3)O(2)P)(3)(H(2)O)], the Ca(2+) 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 CCl(3) 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.
