Synthesis, spectral and crystallographic studies of coordination compounds of some d and f metals with N-nitrozo-N-(methyl)ethylhydroxylamine

Eleven complexes of some d and f metals with N-nitrozo-N- methylhydroxylamine (NMHA) and N-nitrozo-N-ethylhydroxylamine (NEHA) were synthesized, separated out in a crystalline state, and characterized by a set of physicochemical methods (elemental analysis, X-ray diffraction, IR and UV spectroscopy). The crystal and molecular structure of Cu(NEHA)2 was solved using X-ray diffraction. The composition and stability constants of the complexes in solutions were determined spectrophotometrically. The organic ligands were shown to be coordinated to the metal cation in the bidentate chelate mode in the anionic form. © 2014 Pleiades Publishing, Ltd.
