Abstract: In the molecules of 5-amino-1-phenyltetrazole, C₇H₇N₅, (I), and 5-amino-1-(1-naphthyl)tetrazole, C₁₁H₉N₅, (II), the tetrazole rings and aryl fragments are not coplanar; corresponding dihedral angles are 50.58 (5) and 45.19 (7)° for the two independent molecules of (I), and 64.14 (5)° for (II). Intermolecular N-HN hydrogen bonds between the amino groups and tetrazole N atoms are primarily responsible for formation of two-dimensional networks extending parallel to the bc plane in both compounds. The presence of the amino group has a distinct effect on the geometry of the tetrazole rings in each case.

Formula: C₇H₇N₅ and C₁₁H₉N₅
