Applying the concept of octet rule and the Kiremire equation to a given hydrocarbon molecular formula , suitable structures of isomers can be constructed. In this paper, it is shown that the Kiremire equation can be applied to both the neutral and ionic boranes. The equation is related to the Lipscomb symbols by K = s +2t +y. In this way, the Kiremire equation may be considered to complement the Lipscomb?s numbers utilized in the construction of valence bond molecular structures of a given boron hydride. The relationship is also a clear testimony that despite the electron deficiency, the borane clusters constitute themselves in such a way as to attain the octet rule around the boron atoms.
