Resumen
The cyanomanganese carbonyls trans-[Mn(CN)(CO)(dppm)2], and cis- and trans-[Mn(CN)(CO)2{P(OR)3}-(dppm)] (R = Ph or Et, dppm = Ph2PCH2PPh2) react with TlPF6 to give [(thf)2Tl(μ-NC)Mn(CO)(dppm)2]-[PF6] 1, [{Tl(μ-NC)MnLx}2][PF6]2 [Lx = cis-(CO)2{P(OR)3}(dppm), R = Ph 2 or Et 3] and [Tl{(μ-NC)MnLx}2]-[PF6][Lx = trans-(CO)2{P(OR)3}(dppm), R = Ph 4 or Et 5] respectively. Complexes 1 and 3 have been structurally characterised by single-crystal X-ray diffraction methods; the former is pyramidal at thallium while the latter provides a rare example of a μ3-κC:κN:κN cyanide ligand N-bonded to two thallium atoms and C-bonded to manganese.
