Diaqua-bis-[5-(pyrazin-2-yl-?N)-3-(pyridin-3-yl)-1,2,4-triazolido-?N]cadmium.

ABSTRACT: In the title compound, [Cd(C(11)H(7)N(6))(2)(H(2)O)(2)], the Cd(II) cation is located on an inversion center and is coordinated by four N atoms from two 5-(pyrazin-2-yl)-3-(pyridin-3-yl)-1,2,4-triazol-ide anions and two water mol-ecules in a distorted octa-hedral geometry. The triazolide ligand is nearly planar: the central triazole ring is oriented at dihedral angles of 4.63?(13) and 8.41?(13)° with respect to the pyrazine and pyridine rings. Inter-molecular O-H?N hydrogen bonds link the mol-ecules into a two-dimensional supra-molecular network parallel to (001).

Project description: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 crystal, classical O-H⋯N and weak C-H⋯O hydrogen bonds and π-π 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).

2-[2,6-Bis(pyrazin-2-yl)pyridin-4-yl]benzoic acid.

Project description:In the title compound, C20H13N5O2, the two pyrazine rings are nearly coplanar with the central pyridine ring, forming dihedral angles of 2.21?(9) and 4.57?(9)°. In contrast, the strong steric hindrance caused by the ortho-carboxyl group on the phenyl ring makes this ring rotate out of the attached pyridine ring plane by 52.60?(9)°. The carboxyl group is twisted from the phenyl ring by 22.6?(1)°. In the crystal, aromatic ?-? stacking inter-actions [centroid-centroid distances = 3.9186?(4) and 3.9794?(5)?Å] occur between the anti-parallel mol-ecules, generating infinite chains along [100]. O-H?O hydrogen bonds connect the chains, leading to the formation of a two-dimensional supra-molecular network parallel to (010). Inter-molecular C-H?N hydrogen bonds are also observed.

Inter-molecular N-H?O and O-H?O inter-actions involving the perchlorate counter-anions extend the monomeric compound into a two-dimensional network parallel to the bc plane.
