catena-Poly[[[bis­(thio­cyanato-κN)zinc]bis­[μ-1,3,5-tris­(1H-1,2,4-triazol-1-yl­meth­yl)benzene-κ²N⁴:N^4′]] mono­hydrate]

In the title complex, {[Zn(NCS)₂(C₁₅H₁₅N₉)₂]·H₂O}_n, the Zn^II ion is located on an inversion centre and is six-coordinated in a distorted octa­hedral geometry, coordinated by N atoms from four bridging 1,3,5-tris­(1,2,4-triazol-1-ylmeth­yl)benzene (ttmb) ligands and two terminal SCN⁻ counter-anions. Two of the three triazol groups in each ttmb ligand link the Zn^II atoms, forming a looped-chain structure along [0-11]. The lattice water molecule shows half-occupancy due to disorder around an inversion centre.
