摘要: Abstract Starting from [M(CO)6], seven-coordinated complexes of tungsten and molybdenum containing the facially coordinating ligands HC(pz)3 (1) MeC(CH2PPh2)3 (2) were obtained in a two-step reaction sequence. The have 4:3 piano stool geometry with almost perfect CS symmetry crystal. In solution, they show typical fluxional behavior for even at low temperature. Complete oxidative decarbonylation occurs when [HC(pz)3Mo(CO)3] (4) or [MeC(CH2PPh2)3Mo(CO)3] (6) are treated an excess I2 Br2.
