Abstract
Several new ruthenium-nitrosyl conjugates with meso-4'pyridylporphyrins, namely the two anionic isomers [nBu4N][trans-RuCl4(4'MPyP)(NO)] and [nBu4N][cis-RuCl4(4'MPyP)(NO)] , the two neutral isomers [mer,trans-RuCl3(4'MPyP)2(NO)] and [mer,cis-RuCl3(4'MPyP)2(NO)], and the tetraruthenated adduct [nBu4N]4[4'TPyP{RuCl4(NO)}4] were obtained by reaction of [nBu4N][trans-RuCl4(dmso)(NO)] with 4'MPyP and 4'TPyP (meso-4'monopyridylporphyrin and meso-4'tetrapyridylporphyrin, respectively). Exchange of nBu4N+ for Na+ eventually led to the water soluble tetraruthenated porphyrin Na4[Zn 4'TPyP{RuCl4(NO)}4].
