The synthesis of new molybdenum and tungsten carbonyl complexes with the mixed donor bidentate ligands o-Ph2PC6H4-CH=NR is described. Two series of complexes [M(CO)4(o-Ph2PC6H4-CH=NR)] (M = Mo; R = Me (1a), Et (2a), (i)Pr (3a), (t)Bu (4a), NH-Me (5a). M = W; R = Me (1b), Et (2b), (i)Pr (3b), (t)Bu (4b), NH-Me (5b)) have been prepared by direct reaction of the ligands with the corresponding precursors cis-[M(CO)4(pip)2] (M = Mo or W; pip = piperidine NHC5H10). The new complexes were characterized by partial elemental analyses and spectroscopic methods (IR, 1H, 13C and 31P NMR). The molecular structure of compound 1a (monoclinic, P21/n) was determined by a single-crystal diffraction study. (C) 2000 Elsevier Science S.A.
