catena-Poly[[[bis-(thio-cyanato-κN)zinc]bis-[µ-1,3,5-tris-(1H-1,2,4-triazol-1-yl-meth-yl)benzene-κ(2)N(4):N(4')]] mono-hydrate].

In the title complex, {[Zn(NCS)(2)(C(15)H(15)N(9))(2)]·H(2)O}(n), the Zn(II) ion is located on an inversion centre and is six-coordinated in a distorted octa-hedral geometry, coordinated by N atoms from four bridging 1,3,5-tris-(1,2,4-triazol-1-ylmeth-yl)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.

catena-Poly[[chloridocadmium(II)]bis-{µ-1-[(2-ethyl-1H-imidazol-1-yl)meth-yl]-1H-benzotriazole}[chloridocadmium(II)]di-µ-chlorido].

In the polymeric title complex, [CdCl(2)(C(12)H(13)N(5))](n), the Cd(II) atom is five-coordinated by two N atoms from two bridging 1-[(2-ethyl-1H-imidazol-1-yl)meth-yl]-1H-benzotriazole (bmei) ligands, two bridging Cl atoms and one terminal Cl atom in a distorted trigonal-bipyramidal geometry. The Cd(II) atoms are connected alternately by the Cl atoms and bmei ligands, leading to a zigzag chain extending parallel to [011]. π-π inter-actions, with a centroid-centroid distance of 3.3016 (3) Å, help to stabilize the crystal packing.
