Reactions and crystal structures of heterodinuclear complexes R_3Sn-M(CO)_5(M = Mn,Re) with some nitrogen ligands

摘要

Some reactions of R_3SnM(CO)_5(M = Mn,Re) with CH_3CN or pyridine were investigated to give complexes R_3SnMn(CO)_3LL′or R_3SnMn(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.
