Pseudopolymorphism of an adamantane-based bisphenol containing water molecules: a role of clathrate hydrates in hydrogen-bonded networks

An adamantane-based bisphenol (1) assembled into three types of 2D layers with or without channels or a doubly interpenetrated 3D network bearing clathrate hydrates via hydrogen bonds. The different stoichiometries of 1 and water facilitated the formation of the diverse molecular packing structures. Infinite chains and finite triangle clusters of water were formed within the channels and cavities.
