摘要：

Complex formation of 2,3-dimethyl-5-hydroxy-6-aminopyrimidine-4(3H)-one with copper(II) ions in nonaqueous solutions has been studied by means of electron, NMR, and IR spectroscopy as well as mass spectrometry. Sequential formation of tetra- and pentacoordinated copper(II) complexes with mono- and bidentate ligand coordination has been observed. The complexes composition has been determined by spectrophotometry using the molar ratios method. Donor centers of the ligand involved in coordination with copper(II) ions have been determined, and the complexes formation constant have been calculated.
