title: Crystal structure of poly[di-μ-aqua-{5-[(1Z)-2-(4-chloro-phen-yl)-1-cyano-ethenyl]-1,2,3,4-tetra-zol-1-ido-κN (1)}sodium].
abstract: In the title compound, [Na(C10H5ClN5)(H2O)2] n , infinite chains of [Na(H2O)2](+) cations having a diamond-shaped cross-section and running parallel to the b axis are formed. O-H⋯N hydrogen bonds to the anions generate layers parallel to (100) which have the chloro-benzene-cyano-ethenyl substituents protruding from both surfaces. The sodium ion makes a short contact of 2.4801 (13) Å with the N atom of the tetra-zolide ring which is syn to the cyano N atom.
