摘要：

Reaction of (Bu4N)2[Mo6Cli8(CF3SO3)a6] With [CpMn(CO)2CN]-, [CpMn(CO)(NO)CN], or [CpRu(PPh3)2CN] leads to replacement of all six CF3SO3- anions by the organometallic ligands, which are attached through the ambident CN- ligand. The unusual decrease in nu(CN) upon complex formation appears to arise from increased M-C back-pi-bonding and, in one case where it can be assessed, reduced kinematic coupling. A very strong electronic absorption band for these complexes is attributed to mixing of charge transfer with localized transitions. Crystallographic data for (PPN)2[Mo6Cli8{mu-NC)Mn(CO)2Cp}a6]: triclinic space group, P1 (No. 2), a = 17.803-(6) angstrom, b = 19.082(2) angstrom, c = 29.787(6) angstrom, alpha = 73.45(1)degrees, beta = 85.00(2)degrees, gamma = 72.38(2)degrees, V = 9245(7) angstrom3, Z = 3.
