ResumoThe novel, strongly basic, tridentate P-N-ligands PhP(XC 5 H 4 N) 2 l a - c [X = CH 2 (a), O (b), NH (c)] are obtained between -60 and 0 °C by the action of PhPCl 2 on 2-picolyllithium, 2-hydroxy- and 2-aminopyridine, respectively, using NEt 3 and 2-aminopyridine as auxiliary bases, l a - c react with (OC) 3 M(NCCH 3 ) 3 to give the tricarbonyl-P-N-ligand complexes (OC) 3 M[PhP(XC 5 H 4 N) 2 ] 2 - 4 a - c [M = Cr (2), Mo (3), W (4)]. 4c crystallizes in the monoclinic space group P2i/n with Z = 4 and contains two five-membered, slightly distorted chelate rings.
