title: Crystal structure of dissymmetrically trihydrated N,N',N''-tribenzoylmelamine (TBM).
abstract: In the crystal structure of TBM-trihydrate three waters of crystallization were found to locate dissymmetrically. Thus, one of them forms a chelated ring with the neighboring C=O and N-H of TBM. Two other ones bind each other through hydrogen bonding and two sets of which form a cyclic dimer by hydrogen bonding (namely, water-tetramer). A C=O group binds by hydrogen bonding to each of the tetrameric water. The spatial volume occupied by water-tetramer appears to be sufficient for complexation with organic molecules.
