title: [1-(4-Hydroxy-phen-yl)-1H-tetra-zol-5-ylsulfan-yl]acetic acid.
abstract: The title compound, C(9)H(8)N(4)O(3)S, shows a layer structure constructed from inter-molecular O-H⋯O and O-H⋯N hydrogen bonds. Inter-atomic distances suggest that extensive, but not uniform, π-electron delocalization is present in the tetra-zole rings and extends over the exocyclic C-S bond.
