Co-ordination chemistry of the organometallic tridentate ligand trans-[Ru(2-Ph2PC5H4N-P)2(CO)3] and crystal structures of metal complex derivatives

Abstract

The complex trans-[Ru(2-Ph 2PC 5H 4N-P) 2(CO) 3] 1 reacted with Lewis acids such as ZnCl 2, CdCl 2, Cd(ClO 4) 2 and HgCl 2 to give a series of heterometallic [RuM(μ-2-Ph 2PC 5H 4N) 2X(X′)] (M = Zn, Cd or Hg; X = Cl; X′ = Cl, ClO 4 or HgCl 3). Crystal structures of [RuZn(μ-2-Ph 2PC 5H 4N) 2(CO) 3Cl 2] 2, [RuCd(μ-2-Ph 2PC 5H 4N)2(CO) 3Cl 2]·MeOH 3· MeOH, [RuCd(μ-2-Ph 2PC 5H 4N) 2(CO) 3(ClO 4) 2]·CHCl 3 4·CHCl 3 and [RuHg(μ-Ph 2PC 5H 4N) 2(CO) 3Cl][HgCl 3] 5 were determined with Ru-Zn (2), Ru-Cd (3), Ru-Cd (4) and Ru-Hg (5) distances being 2.659(1), 2.771(1), 2.705(1) and 2.622(1) Å, respectively. Different co-ordination modes are present in these heterometallic complexes and their spectroscopic properties were studied. The donor-acceptor bonding interactions of complexes 2-5 are discussed.
