Characterization of the reported [Mn(CO)(Ph2PCH2CH2PPh2)2](red isomer) as the acylmanganese complex [Mn(CO)(COC6H4PhPCH2CH2PPh2)(Ph2PCH2CH2PPh2)] by X-ray diffraction

Abstract

One of the products of the reaction between [Mn₂(CO)₁₀] and Ph₂PCH₂CH₂PPh₂, previously identified as a paramagnetic species [Mn(CO)(Ph₂PCH₂CH₂PPh₂)₂], is in fact diamagnetic and contains an acyl carbonyl group linking the manganese to an ortho carbon of one phenyl ring and is correctly formulated as [Mn(CO)(COC₆H₄PhPCH₂ CH₂PPh₂)(Ph₂PCH₂ CH₂PPh₂)].
