Syntheses and crystal structures of ruthenium complexes with bidentate salicylaldiminato and dithiophosphato ligands

Abstract

Abstract Treatment of the bidentate Schiff base 2-[(2,6-diisopropyl-phenylimino)-methyl]-phenol (HL1) with one equivalent of (Et4N)[RuCl4(MeCN)2] in the presence of triethylamine afforded (Et4N)[RuCl3(κ 2-N,O-L1)(MeCN)] (1), which reacted with two equivalents of K[S2P(O i Pr)2] to produce a neutral ruthenium(III) complex [Ru(κ 2-N,O-L1){η 2-S2P(O i Pr)2}2] (2) bearing both salicylaldiminato and dithiophosphato ligands. Reactions of the bidentate Schiff bases 2-[(3-chloro-phenylimino)-methyl]-phenol (HL2) and 2-[(2,4,6-trimethyl-phenylimino)-methyl]-phenol (HL3) with one equivalent of [Ru(CO)2Cl2] in the presence of triethylamine led to formation of the corresponding anionic ruthenium(II) carbonyl complexes (Et3NH)[RuCl2(κ 2-N,O-L2)(CO)2] (3) and (Et3NH)[RuCl2(κ 2-N,O-L3)(CO)2] (4). The molecular structures of complexes 2–4 have been determined by single-crystal X-ray diffraction.
