The metathesis of CpMn(CO)(NO)SnCl3 (I) and anionic carbonyls (ML-) Mn(CO)5-, Co(CO)4-, CpMo(CO)3-, CpW( CO)3-, CpMo(CO)3- provided trinuclear mixed-metal complexes of general formula CpMn(CO)(NO)SnCl2ML (VIII-XII; Cp = C5H5, Cp′ = C5H4CH3, Cp″ = C 5H3(C4H9)2). Along with XII, the product of transmetallation Cp″Mo(CO)3SnCl3 (XIII) was separated. Interaction of I with Fe2( CO)82- gave the mixed-metal cluster Cp(CO)(NO)Mn-SnCl 2-Fe(CO)4-SnCl2-MnCp(CO)(NO) (XIV) which contain the pentanuclear metal-chain. As determined by the single crystal XRD analysis, the Mn-Sn distance in CpMn(CO)(NO)Sn fragment is 0.2 shorter than the expected value based on the Mn/Sn sum of covalent radii (SCR). From the other hand, the shortening of Sn-ML distances is in an accord with the donor ability of an ML fragment in the row Co(CO)4 ∼ Mn(CO)5 < Fe(CO)4 < CpMn(CO)(NO < Cp′Mo(CO)3 < Cp′W(CO)3 < Cp″Mo(CO)3 owing to the additive back donation of the transition metal d-LEP to Sn vacant orbitals. The absence of substantial elongation of the Sn-Cl distances may result from the π-back donation of transition metal d-orbitals to tin d-orbitals.
