| Abstract: | A novel hypothetical 4,8-connected tetragonal crystalline structure with a ternary stoichiometry AB2C2 is described. The novel pattern belongs to the space group P4/mmm (no. 123). The structure includes novel 8-connected anticube-centered vertices along with ordinary 8-connected cube-centered and 4-connected square-planar vertices. The structure may be representative of a ternary bimetallic fluoride, such as MRe2F2 or MTa2F2, where M is an alkaline-earth metal. The novel structure is unusual due to the absence of strains. |
