Abstract

The complex trans-[Ru(2-Ph2PC5H4N-P)2(CO)3] 1 reacted with Lewis acids such as ZnCl2, CdCl2, Cd(ClO4)2 and HgCl2 to give a series of heterometallic [RuM(µ-2-Ph2PC5H4N)2X(X′)] (M = Zn, Cd or Hg; X = Cl; X′ = Cl, ClO4 or HgCl3). Crystal structures of [RuZn(µ-2-Ph2PC5H4N)2(CO)3Cl2] 2, [RuCd(µ-2-Ph2PC5H4N)2(CO)3Cl2]·MeOH 3· MeOH, [RuCd(µ-2-Ph2PC5H4N)2(CO)3(ClO4)2]·CHCl3 4·CHCl3 and [RuHg(µ-2-Ph2PC5H4N)2(CO)3Cl][HgCl3] 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.
