Interaction of copper(II) halides with 4-(piperidyl-1)-2-phenylpyrido[2,3- a]anthraquinone-7,12 (L) in acidic media: Crystal structure and spectral characteristics of (HL)2[Cu2Cl6] and (HL)[CuBr2]
4-(Piperidyl-1)-2-phenylpyrido[2,3-a]anthraquinonium-7,12 hexachlorodicuprate(II) and 4-(piperidyl-1)-2-phenylpyrido[2,3-a] anthraquinonium-7,12 dibromocuprate(I) are isolated in the crystalline state and investigated using X-ray diffraction. It is established that the Cu(II) cation is reduced to the Cu(I) cation during the synthesis of anionic bromocuprate complexes in the presence of hydrobromic acid. The spectral characteristics of the prepared compounds are discussed. © 2008 Pleiades Publishing, Ltd.
