Popis: X-Ray crystallographic analysis of (μ-p-CH3C6H4NC)Mn2(Ph2PCH2PPh2)2(CO)4 is reported. The molecule consists of two manganese atoms joined by a single bond and bridged by two trans diphosphine ligands and the isocyanide. There are two terminal CO groups per Mn. The isocyanide carbon donates a pair of electrons to one Mn (MnC = 1.81 A) while the CN unit donates a second pair of electrons to the other Mn (MnN = 2.12 A, MnC = 2.14 A). The isocyanide is strongly bent with a CNC(phenyl) angle of 137°. The bonding of the isocyanide ligand is discussed.
