Rhombellane space filling

A space-filling polyhedron is a polyhedron that can tessellate the 3D space. The complete bipartite graph K2.3 is the graph representation of [1,1,1]-propellane, a synthesized molecule, or rather of its reduced form, appearing in the polymer called staffane, with all rings being rhombs/squares. Further, the complete bipartite graphs K2.n represent generalized [1,..,1n]-propellanes, in the following named rhombellanes; they are involved in the space-filling within rhombic arrays. This paper presents construction of some crystals and quasicrystals consisting of rhombellanes, and their characterization in crystallographic terms (by connectivity and ring signature) and in topological terms (by Omega polynomial).
