UNUSUAL TYPES OF LAYERED ORGANIC CRYSTAL HYDRATES
A.M.Banaru, E.S.Mammadov

In molecular crystalline hydrates with a high content of crystallization water infinite H2Ohttps://akj.az.OH2 nets or finite fragments of such nets are formed. As a rule, these nets contain 5- and 6-membered cycles (H2O)n. Brand new topological types of layered organic crystal hydrates among the structures included in the Cambridge Structural Database  in 2009–2019 were found and investigated. The discovered nets were deposited to the Topological Types Database. Topological characteristics of new nets are described, in particular, the maximum possible symmetry, information indices, vertex, edge and face transitivity of the nets
