Studies of phosphazenes. Part 34. Group 6 metal carbonyl complexes of bis(pyrazolyl)cyclotriphosphazenes

Abstract

Reactions of the bis(3,5-dimethylpyrazol-1-yl)cyclotriphosphazenes gem-N3P3Ph4(C3HN2Me2)2(L1) and N3P3(MeNCH2CH2O)2(C3HN2Me2)2(L2) with [M(CO)6](M = Mo or W) afford complexes of the type [M(CO)3 L](L = L1 or L2), which have been characterised by IR and NMR spectroscopic data. The structures of [Mo(CO)3 L1], [W(CO)3 L2] and the ligand L2 have been determined by single-crystal X-ray diffraction. The phosphazenes act as novel tridentate NNN-donor ligands with two pyrazolyl nitrogen atoms and one phosphazene ring nitrogen atom bonded to the metal atom.
