摘要

Abstract

Hydrogermylation is used to obtain new compound, tris(pentafluorophenyl)-2-pyridylethylgermane. The structure is confirmed via IR and NMR spectroscopy, and X-ray diffraction analysis. Thermophysical properties are determined using DSC and TGA. Two polymorphic modifications (triclinic and monoclinic) of tris(pentafluorophenyl)-2-pyridylethylgermane are discovered. It is shown that the triclinic modification is more energetically advantageous than monoclinic modification. The topology of the electron density of tris(pentafluorophenyl)-2-pyridylethylgermane is studied theoretically and experimentally. an intramolecular Ge(1)-N(1) contact is discovered and its energy is estimated from the topology of electron density.
