Crystal structure of aqua-tris-{μ- N-[bis(diethyl-amino)phosphoryl]-2,2,2-tri-chloroacetamidato-κ3O, O': O}calciumsodium

Abstract

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.

Keywords: calcium sodium binuclear compounds; carbacyl­amido­phosphates; crystal structure.
