Abstract

The title compound, [Na2(C10H16Cl3N3O4P)2(H2O)2]n, can be considered as a two-dimensional coordination polymer in which one-dimensional chains are connected to each other by intermolecular C—H...O hydrogen bonds involving the water molecules. The NaI ion is five-coordinated in a distorted trigonal-bipyramidal geometry. The connection between the two NaI ions is facilitated by the two μ-O atoms of the carbonyl group of the 2,2,2-trichloro-N-(dimorpholinophosphoryl)acetamide (CAPh) ligand. A bridging coordination of the CAPh ligand via the carbonyl O atom is observed for the first time. The bridging water molecules form intermolecular O—H...O hydrogen bonds with the O atoms of the morpholine rings and the phosphoryl groups of neighboring CAPh molecules.
