Abstract:
New superalkali phosphide species with the molecular formulas F2Li3P, F2Li3P2, and F4Li6P were investigated. Using the CBS-QB3 composite method to optimize geometry and energetic parameters, four monophosphides, two diphosphides, and one disuperalkali phosphide were discovered that contain intriguing structural features, including hyperlithiation, phosphorus-phosphorus bonds, and planar tetracoordinated phosphorus. It is believed that these features lend to the stability of these structures and may warrant further experimental investigation of these phosphide species to determine if they could play some role in the development of novel chemical reactions and/or materials.

Alkyl Halides
Alkyl halides are halogen-substituted alkanes wherein one or more hydrogen atoms of an alkane is replaced by a halogen atom such as fluorine, chlorine, bromine, or iodine. The carbon atom in an alkyl halide is bonded to the halogen atom, which is sp3-hybridized and exhibits a tetrahedral shape.
Unlike alkyl halides, compounds in which a halogen atom is bonded to an sp2 -hybridized carbon atom of a carbon-carbon double bond (C=C) are called vinyl halides. Whereas aryl...
