The syntheses and structures of four homoleptic metal-metal triply-bonded M2R6 compounds [Mo2(CH2CMe2Ph)6, 1; Mo2(CH2SiMe2Ph)6, 2; W2(CH2SiMe2Ph)6, 3; and W2(CH2Ph)6, 4] are reported. The synthetic effort suggests that ditungsten compounds are inherently more difficult to prepare and more thermally sensitive than dimolybdenum compounds, probably as a result of the larger dimetal core the ligands must protect. The structural data confirm that dimetal hexaalkyls exhibit shorter M≡M distances than do dimetal hexaalkoxides, even in a matched pair case where steric differences are minimal.
