Three new complexes of 1,10‐Phenanthroline (phen), [Ca(phen) 2 (H 2 O) 2 (NO 3 )](NO 3 ) ( 1 ), [Sr(phen) 2 (H 2 O) 2 (NO 3 )](NO 3 ) ( 2 ) and [Ca(phen) 2 (H 2 O) 2 (NO 3 )][BF 4 ] ( 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 (NO 3 ) − is coordinated to the central atom. The other (NO 3 ) − is away from the metal ion and was replaced by [BF 4 ] − under the conditions of a competitive reaction. The two phenanthroline molecules also occupy nonequivalent positions showing typical π – π interactions in their crystal packing.
