Reactions and crystal structures of heterodinuclear complexes R3Sn-M(CO)5 (MÂ =Â Mn, Re) with some nitrogen ligands

Some reactions of R3SnM(CO)5 (M = Mn, Re) with CH3CN or pyridine were investigated to give complexes R3SnMn(CO)3LL′ or R3SnMn(CO)4L by a facile mild method. X-ray diffractions analyses show that, in contrast to the phosphine ligand occupying in axial position, nitrogen ligands occupy equatorial position.
