摘要: The molecular structure of propargylgermane, HCbCCH2GeH3, has been determined by gas-phase electron diffraction. electrondiffraction investigation supported density functional theory and ab initio calculations. ra value the bond lengths (pm) are: r(C–Ge)Z197.2(1); r(C–C)Z143.9(2); r(CbC)Z123.1(1); r(H–Cacetylene)Z108.5(3); r(C–H)Z111.6(3) r(Ge–Haverage)Z153.7(2). Ge–C–C angle is 111.7(1)8 C–CbC 178.3(4)8. uncertainties are one standard deviation from least-squares refinement.
