Tris(2,3,4,5-tetramethylphospholyl)phosphine (1) has been prepared via the reaction of Li(PC4Me4) with PCl3. The structure of 1 was determined by single-crystal X-ray diffraction: triclinic, space group
with a = 8.795(2), b = 11.489(2), c = 14.557(3) Angstrom, alpha = 72.89(3), beta = 88.92(3), gamma = 67.69(3)degrees, V = 1293.4(7) Angstrom(3) and Z = 2.
