Lattice tilings of a plane by polyominos and molecular layers in crystal structures. Structural class cm, Z = 2(m)

Abstract

Abstract. Lattice partitions of a plane into polyominoes were constructed for N from 3 to 12, where N is the order of the packing space. We obtained 5191 symmetric independent lattice partitions of a plane with one polyomino in a reduced (primitive) cell, among which 122 variants belong to the structural class cm, Z = 2(m), with the elementary conventional cell being rectangular (centered). Chain partitions of planes have been derived, for which both structural class and structural subclass were identified. The results of the analysis of lattice partitions of a plane into polyominoes were illustrated with examples of real molecular layers in crystal structures.
Key words: lattice partitions of a plane into polyominoes, molecular layers, molecular chains, structural classes, structural subclasses
