Borane polyhedra as building blocks for unknown but potentially isolatable new molecules: extensions based on computations of the known B18H22 isomers

Abstract

Known borane polyhedral cluster characteristics can be used for predicting new architectural constructs. We propose additional structures derived from B18H22 : three positional isomers different from the well-known anti-B18H22 and syn-B18H22 boranes. We have also derived two new cyclic structures based on the condensation of borane pentagonal pyramids and bipyramids. Borane polyhedral concatenation of molecules is also considered from a mathematical point of view.
