X-Ray crystal structure of a stable metal–5′-uridine monophosphate (UMP) complex, [Cu(5′-UMP)(2,2′-dipyridylamine)(H2O)]2

The ternary complex [Cu(5′-uridine monophosphate)(2,2′-dipyridylamine)(H2O)]2·5H2O has been prepared and structurally characterized by X-ray crystallography; it contains UMP ligands which co-ordinate to copper through the phosphate groups but not through the uracil bases.
