2‐{[2‐(Dimethylamino)ethyl]methylamino}‐1,3,2‐benzodioxaphosphole as a Ligand in Transition‐Metal Complexes. Crystal and Molecular Structure of a Tetracarbonyl Chromium Derivative Complexes of the zerovalent transition metals chromium, molybdenum, iron, and platinum react with the title phosphorus‐(III)‐compound 3 to give a range of different products: in the coordination compounds 4 and 5, 3 functions as a bidentate ligand, coordinating to the metal through the phosphorus and the nitrogen atom of the dimethylamino group. The structure of 4 was confirmed by a single‐crystal X‐ray analysis, showing a ligand “bite” angle of 91.0, 91.4° in two independent molecules. In the compounds 7 – 9 , involving Mo, Fe, and Pt as a central atom, 3 coordinates solely through P(III). For the platinum(O) complex 9 31 P‐NMR spectroscopy revealed a dynamic behaviour at room temperature.
