(Sulfasalazinato-κO)bis-(triphenyl-phosphine-κP)copper(I).

摘要: The title mixed-ligand copper(I) complex, [Cu(C18H13N4O5S)(C18H15P)2], was synthesized via solvothermal reaction of [Cu(PPh3)2(MeCN)2]ClO4 and sulfasalazine [systematic name: 2-hydr­oxy-5-(2-{4-[(2-pyridylamino)sulfon­yl]phen­yl}diazen­yl)benzoic acid]. mononuclear complex displays a trigonal coordination geometry for the Cu(I) atom, which is surrounded by two P-atom donors from different PPh3 ligands one O-atom donor monodentate carboxyl­ate group sulfasalazinate ligand. latter ligand found in zwitterionic form, with deprotonated amine N atom protonated pyridine atom. Such feature previously described free sulfasalazine. crystal structure stabilized C—H⋯O, C—H⋯N, N—H⋯N O—H⋯O hydrogen bonds.
