Experimental Crystal data

R factor = 0.050; wR factor = 0.148; data-to-parameter ratio = 23.2. The crystal structure of the title compound, C15H14N4, contains chains of coplanar tetrazole rings with the chain direction along b. These are formed through weak hydrogen bonds, donated by the tetrazole H atoms and by one of the H atoms of the methylene group, and accepted by two neighbouring N atoms of the adjacent tetrazole ring. The chains are connected to each other in a staircase-like manner via weak hydrogen bonds, donated from the second H atom of the methylene group and accepted by the N atom next to the C atom in the tetrazole ring. The resulting layers are parallel to the bc plane. Related literature For the synthesis, see Kamiya & Saito (1973). For crystal structure studies of 1H-tetrazol-1-yl compounds, see Absmeier et al.
