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): P21/n, a=11.7294(5), b=22.0774(11), c=16.2415(8) Å, β=98.910(5)°; (2): P21/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).
