In contrast, conversion of (C6F5)3GeCl with Si(PH2)4 (1) furnishes 2 a but also the ... crystals in 97% yield and represents the first PH2-substituted germane being structurally characterized by single-crystal ... mixtures of compounds of the type (RO)nSi(PH2)4–n (4, n = 1), (5, n = 2), ...

The synthesis of the following organotellurium(IV) compounds [C4H8TeI{Ph2(Se)PNP(Se)Ph2}] (2), [C4H8TeI{Ph2(S)PNP(S)Ph2}] (3), [C8H8TeI{Ph2(S)PNP(S)Ph2}] (4), [C4H8Te{Ph2(S)PNP(S)Ph2}2] (5), and [O(TeC4H8)2{Ph2(O)PNP(O)Ph2}]2[I, I3] (6) was achieved. These compounds have been characterized by microanalysis, multielement NMR and IR spectroscopy, positive ion FAB mass spectrometry and single-crystal X-ray diffraction analysis. The solid-state structures show that the coordination geometry at the tellurium center ...
