• A series of the ruthenium(II) complexes <B>1–4</B>, [Ru(dabp)<SUB>3−<I>n</I></SUB>(bpy)<I><SUB>n</SUB></I>](BF<SUB>4</SUB>)<SUB>2</SUB> (<I>n</I>=0, 1, 2, and 3, respectively, dabp=6,6′-diamino-2,2′-bipyridine, and bpy=2,2′-bipyridine), having a different degree of interligand steric strain were synthesized, and the effect of the interligand steric strain caused by the amino substituents on their structures was examined. A crystallographic study showed that the two pyridine rings of dabp in the complex <B>1</B> were in a slightly twisted configuration in order to relieve the interligand strain. Similar twisted configurations were suggested for the bipyridine moieties of dabp and bpy in the complexes <B>1–3</B> in dimethyl sulfoxide solution.
