  The preparation of new manganese(II) isocyanide complexes, MnI2(CNBut)n (n=1, 1.5, 2) and the mixed isocyanide/tertiary-phosphine complex MnI2(PPh3)(CNBut)2. The isolation and X-ray crystallographic characterisation of the MnI/MnII mixed-valence isomeric complexes [Mn(CNBut)6][MnI3(PPh3)] and [Mn(CNBut)5(PPh3)][MnI3(CNBut)]

  摘要：

  The complexes MnI2(CNBut)n (n = 1, 1.5 and 2) have been prepared by reaction of MnI2 or MnI2Ln (L = PPh3, THF, n = 2; L = (4-CH3C6H4)3p, n = 1.5) with CNBut in toluene. The reaction of MnI2(PPh3)2 with CNBut in n-pentane slurry gives the complex of formula MnI2(PPh3)(CNBut)2. When MnI2(PPh3)2 reacts with an excess of CNBut in toluene, red-orange crystals of [Mn(CNBut)5(PPh3)][MnI3(CNBut)] and yellow crystals of [Mn(CNBUt)6][MnI3(PPh3)] are formed. X-ray diffraction studies of the two types of crystal show them to have the ion-pair structures. IR studies suggest that in the MnI2(CNBut)n complexes the Mn-C bond is predominantly of sigma-character, whereas in the mixed phosphine/isocyanide derivatives the Mn-C bond is predominantly of pi-character.

  The reaction of bromo- and iodo-phosphoranes with unactivated coarse grain manganese metal powder to yield [MnI₂(phosphine)₂] and [{MnX₂(phosphine)}_n](X = Br or I) by insertion of Mn into the P–X bond. The crystal structure of [MnI₂(PPh₃)₂]

  摘要：

  The novel reaction of crude manganese metal powder with dibromo- and diiodo-phosphoranes, R3PX2, has been studied. Reaction of the phosphoranes R3PI2 (R = phenyl or substituted aryl) with manganese allows insertion of the metal into P-X bonds and gives the monomeric tetrahedral complexes [MnI2(PR3)2] and MnI2. However, reaction of R3PX2 (R3 = mixed aryl/alkyl, trialkyl; X = Br or I) with manganese, whilst once again proceeding via insertion into P-X bonds, now leads to the quantitative isolation of the polymeric complexes [{MnX2(PR3)}n], thus illustrating the subtle nature of these reactions. Examples of both types of complex have been crystallographically characterised and represent rare examples of such. There is some evidence that where R3 = Ph2Me an equilibrium exists and both types of complex, [MnI2(PPh2Me)2] and [{MnI2(PPh2Me)}n] can be detected from the same reaction.
