چکیده
In the title compound, {[Zn(C(9)H(9)N(5))(2)(H(2)O)(2)](ClO(4))(2)}(n), the Zn(II) ion lies on an inversion center and is coordinated by two triazolyl N atoms and two pyridyl N atoms from four symmetry-related N-1-(3-pyrid-yl)ethyl-idene-4H-1,2,4-triazol-4-amine (L) ligands and two O atoms from coordinated water mol-ecules in a slightly distorted octa-hedral environment. Each L ligand bridges symmetry-related Zn(II) ions, forming a two-dimensional layer with a (4,4) grid. In the crystal structure, inter-molecular O-H⋯O hydrogen bonds connect perchlorate counter-anions to the layers.

In the crystal structure of the title 1:2 adduct, [Zn(2)(NCS)(4)(C(4)H(8)N(4))(2)]·2[Zn(NCS)(2)(C(4)H(8)N(4))(2)] or (Ia)·2(Ib), each Zn(II) atom is coordinated in a distorted tetra-hedral geometry by four N atoms from two triazole rings of two 4-amino-3,5-dimethyl-1,2,4-triazole (admt) ligands and two NCS(-) ligands. In (Ia), double N(1):N(2)-bridging admt ligands connect two Zn(II) atoms, for...

In the title complex, [Zn(C(14)H(9)N(5))(2)](ClO(4))(2), 2-(1H-1,2,4-triazol-1-yl)-1,10-phenanthroline functions as a tridentate ligand and the Zn(II) ion assumes a distorted octa-hedral ZnN(6) coordination geometry. There is a weak π-π stacking inter-action between symmetry-related triazolyl rings with a centroid-centroid distance of 3.802 (4) Å and a perpendicular distance of 3.413 Å between ...
