Thermochemistry of germanium and organogermanium compounds

Author affiliations

Abstract

This article reviews the current state of thermochemistry (enthalpies of formation) of germanium and organogermanium compounds. While the emphasis is on data from experimental measurements, results of quantum chemical (ab initio) calculations are also included. We provide a set of current best values for GeX4 compounds (X = H, Me, F, Cl, Br, I) as well as mixed GeXnY4−n compounds. Also included are Ge/C/H, Ge/C/H/O and Ge/C/H/N compounds and Ge2 and Ge3 containing molecules. Further inclusions are data for species such as GeX3 (free radicals), GeX2 (germylenes) and π-bonded molecules which play prominent roles as intermediates in many thermal and photochemical reactions of germanium compounds. Bond dissociation enthalpies are derived for most commonly encountered Ge–X bonds. The evaluation of preferred values is assisted by exploiting relationships (increments, substituent effects) within specific series and between series.
