Abstract
The crystal structure of N,N,N′,N′-tetrakis-[(1H,2,4-triazol-1-yl)methyl]-ethane-1,2-diamine has been fully determined at six different temperatures by X-ray single-crystal diffraction, and the thermal expansion has been determined from 100 K to ambient temperature. The expansion is anisotropic, and it is negative in one direction of the unit cell. The supramolecular structure formed by weak hydrogen bonds of the type C–H···N resembles a trellis analogous to that observed in other organic systems with strong hydrogen bonds.
