1-Phenyl-5-(piperidinomethyl)-1H-tetrazole

In the molecule of the title 1,5-disubstituted tetrazole, C13H17N5, the tetrazole and benzene rings are not coplanar, having a dihedral angle of 42.96 (5)degrees between them. The piperidine fragment adopts a chair conformation, and there is a non-classical intramolecular contact between the benzene H atom and the piperidine N atom. Intermolecular C-H...pi interactions involving the piperidine C-H groups and the benzene rings are responsible for the formation of two-dimensional networks, extending parallel to the ab plane. These networks are linked together into a three-dimensional polymeric structure via pi-pi stacking interactions between the tetrazole rings of two adjacent molecules.
