Structural and models of dioxouranium(VI) with rhodanine azodyes--V.

Abstract The synthesis of several new coordination compounds of dioxouranium(VI) heterochelates with bidentate rhodanineazol compounds derived from rhodanine are described. The ligands and uranyl complexes have been charcaterized by various physico-chemical techniques. The bond lengths and the force constants have been calculated from asymmetric stretching frequency of O–U–O group. The infrared spectral studies showed a monobasic bidentate behaviour with the oxygen and azonitrogen donor system. The ligands contain intramolecular hydrogen bonds.
