Abstract
The crystal and mol. structures of the title compd. were detd. by x-ray diffraction. The structure was solved by Patterson methods and refined by least-squares calcns. to an R of 0.06. The crystals are triclinic, space group P1, with a 18.954(2), b 11.850(1), c 11.143(1) Å, 114.97(1), 94.75(1), and 97.51(1)°; d.(exptl.) = 1.36 and d.(calcd.) = 1.33 for Z = 2. The compd. has square-planar coordination with the phosphine groups trans to each other and the triazenido group acting as a monodentate ligand. The plane of the triazene N atoms contains the Pd atom. The interaction of the N -electrons appears to be absent. A possible mechanism for the fluxional behavior of the mol. is suggested.
