Germanium tetrafluoride is a noncombustible, strongly fuming gas with a garlic-like odor. It reacts with water to form hydrofluoric acid and germanium dioxide. Decomposition occurs above 1000 °C. [5] Reaction of GeF 4 with fluoride sources produces GeF 5 − anions with octahedral coordination around Ge atom due to polymerization. [6]
Xenon tetrafluoride is a colorless crystalline solid that sublimes at 117 °C. Its structure was determined by both NMR spectroscopy and X-ray crystallography in 1963. [ 6 ] [ 7 ] The structure is square planar , as has been confirmed by neutron diffraction studies. [ 8 ]
The GAMESS (US) software also provides a comprehensive bonding analysis technique based on the Quasi-Atomic Orbital (QUAO) analysis proposed by professor Klaus Ruedenberg. The QUAO analysis provides a quasi-atomical perspective of bonding molecular orbitals in molecules. These are oriented orbitals which show the bonding direction.
Spartan is a molecular modelling and computational chemistry application from Wavefunction. [2] It contains code for molecular mechanics , semi-empirical methods , ab initio models , [ 3 ] density functional models , [ 4 ] post-Hartree–Fock models, [ 5 ] and thermochemical recipes including G3(MP2) [ 6 ] and T1.

GEF was initially developed as part of IBM's etools (com.ibm.etools.gef) and was contributed to Eclipse in 2002 in version 2.0.0, consisting then of two components: Draw2d, a 2D visualization component based on the Standard Widget Toolkit (SWT) and GEF (MVC), a related model-view-controller framework that can be used to realize graphical editors as part of Eclipse Rich Client Platform (RCP ...

A notable derivative of GeCl 4 is germanium dioxide.In the manufacture of optical fibers, silicon tetrachloride, SiCl 4, and germanium tetrachloride, GeCl 4, are introduced with oxygen into a hollow glass preform, which is carefully heated to allow for oxidation of the reagents to their respective oxides and formation of a glass mixture.
