Tetraaryl-methane analogues in group 14-4. Ph4−nM(p-Tol)n (n = 0–4, M = Si, Ge, Sn, Pb). Synthesis, structural and spectroscopic data, and semi empirical calculations: Mutual interaction of tetrahedral σ-orbitals (symmetry and electronegativity) and delocalized σ-lumos (π-Lewis acidity)
been synthesized by lithium (M = Si) or Grignard methods (M = Ge, Sn, Pb). The crystal structure of Ph 3 Sn( p -Tol), a survey of the 10 known structures and spectroscopic data (NMR, Mossbauer, IR, Raman) are given. A change of the symmetry of the formally tetrahedral MC 4 backbone arises if M = Si and Ge (elongation along one S 4 or C3 axis) are altered to M = Sn and Pb (contraction along one S 4 axis)
