Abstract:
Two new ionic [Fe( bpy ) 3 ](ONC(CN) 2 ) 2 ·2HONC(CN) 2 ( 1 ) and [Fe( phen ) 3 ](ONC(CN) 2 ) 2 ( 2 ) complexes have been synthesized ( bpy is 2,2′-bipyridine, phen is 1,10-phenanthroline). X-ray structural analysis (( 1 ): P 2 1 / n , a =11.7294(5), b =22.0774(11), c =16.2415(8) Å, β =98.910(5)°; ( 2 ): P 2 1 / c , a =9.4951(3), b =21.6640(9), c =17.3365(6) Å, β =92.483(3)°) revealed that their structures consist of one [Fe( bpy ) 3 ] 2+ or [Fe( phen ) 3 ] 2+ complex cation and two uncoordinated nitrosodicyanomethanide, ONC(CN) 2 - counteranions; two molecules of unique nitrosodicyanomethanide acid HONC(CN) 2 were found in ( 1 ), too. In the cations, the Fe(II) atom is coordinated by six nitrogen atoms of chelate coordinated neutral ligands forming a distorted octahedron coordination geometry. Both structures are stabilized by π-π interactions and hydrogen bonds, which are very strong in ( 1 ).
