Crystal structures of some trinitromethyl derivatives of 1,3,5-triazine

The method of single crystal X-ray diffraction (XRD) is used to study the crystal structures of the following trinitromethyl derivatives of 1,3,5-triazine: 2,4-diazido-6-trinitromethyl-1,3,5-triazine (1), 2,4-dimethoxy-6-trinitromethyl-1,3,5-triazine (2), 2,4-bis(N,N-dimethylamino)-6-trinitromethyl-1,3,5-triazine (3). Some features of the structure (geometry) of the trinitromethyl group and its location relative to the 1,3,5-triazine ring is determined.
