Ruthenium(II) complexes with 2-(diphenylphosphinomethyl)aniline

2-(Diphenylphosphinomethyl)aniline, H2L1, reacts with [RuCl2(PPh3)3] to yield the monomeric complexes [RuCl2(H2L1)(PPh3)(CH3CN)], [RuCl2(H2L1)2] and the chloro-bridged dimer [(H2L1)(PPh3)Ru(μ-Cl)2Ru(PPh3)(H2L1)] depending on the conditions applied. Exclusively the monochelate [RuCl2(H2L1)(dmso)2] is formed during reactions of H2L1 with [RuCl2(dmso)4]. H2L1 acts as a neutral, bidentate ligand in all complexes. The products are studied spectroscopically and by X-ray diffraction.
