title: Non-linear optical crystals of 2,2,3-trimethyl-3-(1H-1,2,3,4-tetrazol-5-yl)butanenitrile.
abstract: The title compound, C(8)H(13)N(5), is a novel functionally substituted 5-alkyltetrazole. The substituent on the tetrazole C atom is symmetrical, with intrinsic symmetry close to m. There is intermolecular N-H.N hydrogen bonding between adjacent tetrazole rings, which is responsible for the formation of one-dimensional polymeric chains running along the c axis. The polycrystalline compound exhibits frequency doubling for incident light (lambda = 1064 nm) from a YAG:Nd pulsed laser.
