A Topological Theory of Boron Hydrides

Without the introduction of some formal arguments which abstract the common structural features of the known hydrides, the three-center

It must be emphasized that this type of topological theory is not limited to three-center bonds. Its extension to other types of semilocal-ized multi-centered molecular orbitals might well prove useful in an extensive study of valence in certain intermetallic compounds in which 

In order to eliminate from consideration certain structural features not present among the known boron hydrides, some further principles may be stated in order of decreasing reliability
