Abstract
This paper describes the crystal structure of a novel, hypothetical 3-,8-connected cubic structural pattern with the binary stoichiometry A3B8. The novel pattern lies in space group Pm3m, number 221. It possesses the Wells point symbol (4468812)3(43)8 and has the Wellsean Schläfli index (6, 4.3636). It is derived from the Andreini space filling arrangement of octahedra and cuboctahedra by replacing the areas where there are face-sharing of the polyhedra with the inscription of 3-connected, trigonal planar vertices, and retaining the points where the polyhedra share vertices in cube coordination. The structure-type could be representative of a binary metal oxide in which the metal cation attains a relatively high oxidation state of 51/3+. Possible metal oxide models for the structure-type include M3O8 (where M is a Group 6 or 7 elements).
