title: catena-Poly[[(1,10-phenanthroline-κN,N')zinc]-μ-4-sulfonato-benzo-triazolido-κN,O:N].
abstract: In the title complex, [Zn(C(6)H(3)N(3)O(3)S)(C(12)H(8)N(2))](n), the Zn(2+) cation is coordinated by two N atoms from two 4-sulfonato-benzotriazolide dianions, two N atoms from a 1,10-phenanthroline mol-ecule and a sulfonate O atom from a 4-sulfonato-benzotriazolide anion, displaying a distorted ZnN(4)O trigonal-bipyramidal geometry. Each 1,10-phenanthroline ligand displays a bidentate chelating coordinating mode and the 4-sulfonato-benzotriazolide ions act as μ(2)-bridges, linking different Zn(2+) cations into a chain along the b axis. The crystal structure is consolidated by C-H⋯O hydrogen-bonding inter-actions.
