Crystal structure of 1,4-bis-[5-(2-meth-oxy-phen-yl)-2-tetra-zol-2-yl]butane.

The title compound, CHNO, was synthesized by the coupling reaction of a sodium tetra-zolate salt and di-bromo-butane in a molar ratio of 2:1. The reaction can produce several possible regioisomers and the title compound was separated as the major product. The X-ray crystallographic study confirmed that the title compound crystallizes in the monoclinic 2/ space group and possesses a bridging butyl-ene group that connects two identical phenyl tetra-zole moieties.
