Coordination compounds of some d metals with nitrophenylhydrazone oxopyridine (pyrimidine) derivatives: Crystal and molecular structure of C 10H9N5O6

Twelve new d-metal complexes with 5-[(4-nitrophenyl)hydrazo]pyrimidine-2,4, 6-trione (HL1) and 4-methyl-5-[4-nitrophenylhydrazo]-2,6-dioxo-1,2,5, 6-tetrahydropyridine-3-carbonitryl (HL2) have been synthesized and separated out in the crystalline state. The crystal and molecular structures of HL1 have been solved by X-ray diffraction analysis. The organic molecule exists in the crystalline state as a planar hydrazo tautomer stabilized by intramolecular hydrogen bonds. Metal coordination is bidentate chelate. The acid-base equilibria and complexation of the ligands in solutions have been studied, and the complexation constants have been found. © 2013 Pleiades Publishing, Ltd.
