Structural Classes With a Sole Bearing Contact of Chained Structural Units

Abstract

Structural classes of the crystal structures consisting of mutually parallel chains of structural units (polymers) and constructed due to the sole bearing contact between polymer chains have been derived. In total, 43 structure classes have been found. Nets of bearing contacts in these classes belong to topological types sql, hxl, hcb, kgm, kgd, 2,4L2 and some other types of nets with doubly coordinated vertices. Examples of crystal structures of inorganic and organic polymers are presented.
