The phenylene ring is twisted out of the tetrazolium plane by 42.18 (7)¡ã. Relatively short distances [3.7572 (9) and 4.0625 (6) ] between the centroids of the phenylene and tetrazolium rings of neighbouring molecules suggest ¦Ð¨C¦Ð interactions. The crystal under investigation was a non-merohedral twin, with a 33% twin component. %U http://scripts.iucr.org/cgi-bin/paper?S1600536809026683
