Graph theory-derived methods are used to derive the chemical bonding topology of the closed-shell Rh/sub 4/B/sub 4//sup 4 -/ building blocks of the superconducting lanthanide rhodium borides, LnRh/sub 4/B/sub 4/ (Ln = lanthanides such as Nd, Sm, Er, Tm, Lu). The resulting chemical bonding topology consists of edge-localized Rh/sub 4/ tetrahedra electronically linked in a three-dimensional lattice by exotetrahedral Rh-Rh bonds. This work thus provides an example of an additional class of relatively high-temperature superconductors exhibiting porously delocalized chemical bonding topology like the Chevrel phases discussed in the previous paper of this series.
