Dipotassium tetra-aqua-bis-[3,5-bis-(dicyano-methyl-ene)cyclo-pentane-1,2,4-trionato(1-)-?N]cobaltate(II).

ABSTRACT: The title structure, K(2)[Co(C(11)N(4)O(3))(2)(H(2)O)(4)], is isotypic with K(2)[Fe(C(11)N(4)O(3))(2)(H(2)O)(4)]. The Co(II) atom is in a distorted octa-hedral CoN(2)O(4) geometry, forming a dianionic mononuclear entity. Each dianionic unit is associated with two potassium cations and inter-acts with adjacent units through O-H?N and O-H?O hydrogen bonds.

Crystal structure of tetra-aqua-bis(3,5-di-amino-4H-1,2,4-triazol-1-ium)cobalt(II) bis-[bis-(pyridine-2,6-di-carboxyl-ato)cobaltate(II)] dihydrate.

Project description:The asymmetric unit of the title compound, [Co(C2H6N5)2(H2O)4][Co(C7H3NO4)2]2·2H2O, features 1.5 Co(II) ions (one anionic complex and one half cationic complex) and one water mol-ecule. In the cationic complex, the Co(II) atom is located on an inversion centre and is coordinated by two triazolium cations and four water mol-ecules, adopting an octa-hedral geometry where the N atoms of the two triazolium cations occupy the axial positions and the O atoms of the four water mol-ecules the equatorial positions. The two triazole ligands are parallel offset (with a distance of 1.38 Å between their planes). In the anionic complex, the Co(II) ion is six-coordinated by two N and four O atoms of the two pyridine-2,6-di-carboxyl-ate anions, exhibiting a slightly distorted octa-hedral coordination geometry in which the mean plane of the two pyridine-2,6-di-carboxyl-ate anions are almost perpendicular to each other, making a dihedral angle of 85.87 (2)°. In the crystal, mol-ecules are linked into a three-dimensional network via C-H⋯O, C-H⋯N, O-H⋯O and N-H⋯O hydrogen bonds.

Aqua-bis(3,5-dimethyl-1H-pyrazole-κN)(oxalato-κO,O')copper(II).

Project description:In the title compound, [Cu(C(2)O(4))(C(5)H(8)N(2))(2)(H(2)O)], the Cu(II) atom is coordinated in a slightly distorted square-pyramidal geometry by two N atoms belonging to the two 3,5-dimethyl-1H-pyrazole ligands, two O atoms of the oxalate anion providing an O,O'-chelating coordination mode, and an O atom of the water mol-ecule occupying the apical position. The crystal packing shows a well defined layer structure. Intra-layer connections are realised through a system of hydrogen bonds while the nature of the inter-layer inter-actions is completely hydro-phobic, including no hydrogen-bonding inter-actions.

Bis[triaqua-(1H-1,2,4-triazole-3,5-dicarboxyl-ato-?O,N)copper(II)] di-?-aqua-bis-[diaqua-(1H-1,2,4-triazole-3,5-dicarboxyl-ato-?O,N)copper(II)].

Project description:In the title compound, [Cu(C(4)HN(3)O(4))(H(2)O)(3)](2)[Cu(2)(C(4)HN(3)O(4))(2)(H(2)O)(6)], both monomeric and dimeric mol-ecules are present in the solid state. In the monomeric compound, the Cu(II) atom is five-coordinated in a square-pyramidal configuration by one O atom and one N atom from one 1H-1,2,4-triazole-3,5-dicarboxyl-ate (TZDCA(2-)) ligand and three O atoms from water mol-ecules. In the centrosymmetric binuclear complex, each Cu(II) atom is six-coordinated in an octa-hedral geometry by one O atom and one N atom from one TZDCA(2-) ligand and four O atoms from water mol-ecules, two of which bridge the Cu(II) atoms. In the structure, there are intra-molecular O-H?O and N-H?O hydrogen bonds, and in the crystal, inter-molecular O-H?O, O-H?N and N-H?O hydrogen bonds link symmetry-related mol-ecules, forming a three-dimensional supra-molecular structure.

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

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 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 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.

Di-μ-chlorido-bis-{[4-amino-3,5-bis-(2-pyrid-yl)-4H-1,2,4-triazole-κN]chloridomercury(II)}.

Project description:In the centrosymmetric binuclear title complex, [Hg(2)Cl(4)(C(12)H(10)N(6))(2)], the Hg(II) ion is five-coordinated by two N atoms and three chloride ions with a distorted square-pyramidal geometry. In the complex, there is an intra-molecular N-H⋯N hydrogen bond. In the crystal, the binuclear units are connected by inter-molecular N-H⋯Cl hydrogen bonds, as well as π-π stacking inter-actions [centroid-centroid distances = 3.526 (2) and 3.696 (2) Å], forming a two-dimensional layered structure parallel to (010).

Dipotassium hexa-aqua-nickel(II) bis-[hexa-fluoridozirconate(IV)].

Project description:Single crystals of the title compound, K(2)[Ni(H(2)O)(6)][ZrF(6)](2), were grown by slow evaporation of a 40% aqueous HF solution in which a stoichiometric mixture of NiCl(2)·6H(2)O, ZrF(4) and KCl was dissolved. The monoclinic structure is isotypic with its K(2)Cu, K(2)Zn, Cs(2)Zn and Cs(2)Cu analogues. The structure is built up from isolated, slightly elongated octa-hedral [Ni(H(2)O)(6)](2+) complex cations (symmetry ) and dimeric [Zr(2)F(12)](4-) complex anions (symmetry ) that are also isolated from each other. The [Zr(2)F(12)](4-) anion results from the association of two distorted penta-gonal-bipyramidal [ZrF(7)] coordination polyhedra by sharing an equatorial edge passing through an inversion center of the unit cell. Both isolated [Ni(H(2)O)(6)](2+) and [Zr(2)F(12)](4-) complex ions are situated in planes parallel to (010). They are connected by the eight-coordinated K(+) ions into a three-dimensional structure. An intricate O-H?F hydrogen-bonding network consolidates the structure.
