摘要
The crystal structure of the title compound, C7H8N3+.-NO3-, contains four independent molecules. Molecules 1 and 2 are related by local pseudo 2(1)/b symmetry (a axis unique). Molecules 3 and 4 are related by a local pseudo 2(1)/a symmetry (b axis unique). The layer containing molecules 1 and 2 can be transformed to the layer containing molecules 3 and 4 by a rotation of 90 degrees about a local axis perpendicular to the (001) plane plus a translation of c/2. The cations and anions are connected by hydrogen bonding to form flat ribbons.
