Abstract
Three new complexes of 1,10‐Phenanthroline (phen), [Ca(phen)2(H2O)2(NO3)](NO3) (1), [Sr(phen)2(H2O)2(NO3)](NO3) (2) and [Ca(phen)2(H2O)2(NO3)][BF4] (3) were synthesized and characterized by UV, FT IR, Raman, and MS spectra. Their crystal structures were also determined. In 1 and 2 only one of the (NO3)− is coordinated to the central atom. The other (NO3)− is away from the metal ion and was replaced by [BF4]− under the conditions of a competitive reaction. The two phenanthroline molecules also occupy nonequivalent positions showing typical π – π interactions in their crystal packing.Keywords
