Abstract : The organothallium phosphorus adduct (Me3SiCH2)3Tl-P(SiMe3)3 (1) was prepared by combining (Me3SiCH2)3Tl and P(SiMe3)3 at room temperature. Compound 1 was characterized by 1H, 13C(1H), and 31P(1H) NMR, partial elemental analysis, El mass spectrometry, and single-crystal X-ray analysis, the first to be reported for a thallium-group 15 adduct. Crystal data for 1: trigonal system, space group P 31,, with a = 16.063(6) A, c = 12.148(3) A, Dcalcd = 1.315 g cm-3, and V = 2714.3(11) A3 for Z = 3. Refinement converged at R =0.042 (Rw = 0.045). The Tl-P bond length in 1, previously unreported for compounds of this type, was found to be 2.922(3) A.
