reaction of 2 with [Mo(CO)4(NBD)] produces cis-[(EtNP(OC6H3Me2-2,6)2}2)Mo(CO)4] (5). Diphosphazanes 1–4 and the metal derivative 5 have been characterized by means of their analytical data and EI-MS, IR and multinuclearNMR (1H and 31P) spectral data. The solid-state structure of the diphosphazanes 1, 2 and 4, and the molybdenum complex 5 have been determined by X-ray diffraction studies. Irrespective
