Abstract:
Recent work has shown that BO(2) which is a superhalogen with an electron affinity of 4.46 eV, can be used as building block of a new class of molecules/clusters whose electron affinities can exceed that of BO(2). This class of molecules was named hyperhalogens and the concept was illustrated by focusing on Au(BO(2))(2). Here we explore other superhalogens besides BO(2) to see if they too can be used to form hyperhalogens. We have chosen to focus on AlO(2) which is valence isoelectronic with BO(2) as well as VO(3) which involves a transition metal atom. The results obtained using density functional theory show unexpected behavior: Although AlO(2) and VO(3) are both superhalogens such as BO(2), only Na(BO(2))(2) is a hyperhalogen while Na(AlO(2))(2) and Na(VO(3))(2) are not. The origin of this anomalous result is traced to the large binding energy of the dimers of AlO(2) and VO(3).

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...
