Di-aqua-bis-[5-(pyrazin-2-yl-?N (1))-3-(pyridin-3-yl)-1,2,4-triazolido-?N (1)]zinc.

ABSTRACT: In the title compound, [Zn(C11H7N6)2(H2O)2], the Zn(II) cation, located on an inversion center, is N,N'-chelated by two 5-(pyrazin-2-yl)-3-(pyridin-3-yl)-1,2,4-triazolide anions and is further coordinated by two water mol-ecules in a distorted N4O2 octa-hedral geometry. In the anionic ligand, the pyrazine and pyridine rings are twisted with respect to the central triazole ring by 5.77?(10) and 11.54?(10)°, respectively. In the crystal, classical O-H?N and weak C-H?O hydrogen bonds and ?-? stacking inter-actions between aromatic rings [the centroid-centroid distances between triazole and pyrazine rings, and between triazole and pyridine rings are 3.623?(2) and 3.852?(2)?Å, respectively] connect the mol-ecules into a three-dimensional supra-molecular architecture.

Diaqua-bis-[5-(pyrazin-2-yl)-3-(pyridin-4-yl)-1H-1,2,4-triazol-1-ido-κN]zinc.

Project description:The title mononuclear complex, [Zn(C(11)H(7)N(6))(2)(H(2)O)(2)], is composed of one Zn(II) ion, two deprotonated ppt ligands [Hppt = 5-(pyrazin-2-yl)-3-(pyridin-4-yl)-1H-1,2,4-triazole] and two coordinating water mol-ecules. The asymmetric unit consists of one half-mol-ecule that is completed by application of a centre of symmetry. The Zn(II) atom is six-coordinated in an octa-hedral environment, surrounded by two O atoms in the axial positions and four N atoms in the equatorial plane. Adjacent mononuclear units are further linked via O-H⋯N hydrogen-bonding inter-actions, forming a two-dimensional network along (100).

Di-aqua-bis-{?-1,5-bis-[(pyridin-2-yl)methyl-idene]carbonohydrazide(1-)}di-?-chlorido-tetra-chlorido-tetra-zinc(II).

Project description:A tetra-nuclear ZnII complex, [Zn4(C13H11N6O)2Cl6(H2O)2] or {[Zn2(HL)(H2O)(Cl2)](?Cl)2[Zn2(HL)(H2O)(Cl)]}2, was synthesized by mixing an equimolar amount of a methanol solution containing ZnCl2 and a methanol solution containing the ligand H2 L [1,5-bis-(pyridin-2-yl-methyl-ene)carbono-hydrazide]. In the tetra-nuclear complex, each of the two ligand mol-ecules forms a dinuclear unit that is connected to another dinuclear unit by two bridging chloride anions. In each dinuclear unit, one ZnII cation is penta-coordinated in a N2OCl2 in a distorted square-pyramidal geometry, while the other ZnII cation is hexa-coordinated in a N3OCl2 environment with a distorted octa-hedral geometry. The basal plane around the penta-coordinated ZnII cation is formed by one chloride anion, one oxygen atom, one imino nitro-gen atom and one pyridine nitro-gen atom with the apical position occupied by a chloride anion. The basal plane of the hexa-coordinated ZnII cation is formed by one chloride anion, one hydrazinyl nitro-gen atom, one imino nitro-gen atom and one pyridine nitro-gen atom with the apical positions occupied by a water oxygen atom and a bridged chloro anion from another dinuclear unit, leading to a tetra-nuclear complex. A series of intra-molecular C-H?Cl hydrogen bonds is observed in each tetra-nuclear unit. In the crystal, the tetra-nuclear units are connected by inter-molecular C-H?Cl, C-H?O and N-H?O hydrogen bonds, forming a planar two-dimensional structure in the ac plane.

Of the two water H atoms, one participates in an intra-molecular hydrogen bond whereas the second participates in an inter-molecular hydrogen bond, which leads to the formation of a chain along [010].
