Reactions of NaMn(CO)5 with RuCl2(PMe3)4, RuCl2(dppm)2 and RuCl2(PPh3)3 lead either to an ionic species + - or to metal-metal bonded Ru-Mn compounds such as RuMn(μ-CO)2(CO)3(μ-dppm)2Cl, and, quite unexpectedly, to the μ-phosphido complex RuMn(μ-PPh2)(CO)6(PPh3)2 via a hydride intermediate.

The possibility of making metal-metal bonded heterobimetallic species by metathesis of ruthenium dichlorides with anionic carbonylates is demonstrated by the isolation of MoRu(μ-Cl)(CO)2(PPh3)2(η-C5H5) (1) and MnRuCl(μ-CO)2(CO)3(μ-dppm)2 (2), obtained by action of - on RuCl2(PPh3)3 and of Mn(CO)5- on RuCl2(dppm)2, respectively.In contrast, reaction of Mn(CO5)- with RuCl2(PMe3)4 yielded an ionic species 3 containing the diruthenium cation Ru2Cl3(PMe3)46+.More interestingly, the action of Mn(CO)5- on RuCl2(PPh3)3 resulted in formation of the unexpected complex MnRu(μ-PPh2)(CO)6(PPh3)2 (4) in which the phosphido group PPh2 bridges the two metals; this process is shown to involve a hydride intermediate, and elimination of a molecule of benzene, both identified in the reaction mixture.
