The isolation and spectrosocopic characterisation of six complexes, cis-[M(CO)4L2] (M = Mo, W), fac-[Mo(CO)3(NCMe)L2], fac-[M′Br(CO)3L2] (M = Mn, Re) and fac-[Re(CO)3(NCMe)L2]ClO4, are reported with L2 = the Schiff base ligand 2,6-bis[1- (phenylimino)ethyl]pyridine. This ligand, which has previously been shown to act as a planar tridentate in a wide range of complexes, behaves as a bidentate chelating ligand in all the above complexes bonding through the pyridyl nitrogen and one imine nitrogen only.
