Synthesis, crystal structure and Hirshfeld surface analysis of bis-{2-[(pyridin-2-yl)amino]-pyridinium} tetra-cyano-nickelate(II).

ABSTRACT: In the title mol-ecular salt, (C10H10N3)2[Ni(CN)4], the dihedral angle between the pyridine rings in the cation is 1.92?(13)° and the complete anion is generated by a crystallographic centre of symmetry. An intra-molecular N-H?N hydrogen bond occurs in the cation, which closes an S(6) ring. In the crystal, the components are linked by N-H?N and weak C-H?N hydrogen bonds, which generate chains propagating in the [101] direction. Weak aromatic ?-? stacking inter-actions are also observed. A Hirshfeld surface analysis and two-dimensional fingerprint plots indicate that the most important contact types in the crystal packing are N?H/H?N, C?H/H?C and H?H with contributions of 37.2, 28.3 and 21.9%, respectively.

In the title mol-ecular salt, (C10H10N3)2[Ni(CN)4], the dihedral angle between the pyridine rings in the cation is 1.92 (13)° and the complete anion is generated by a crystallographic centre of symmetry. An intra-molecular N-H⋯N hydrogen bond occurs in the cation, which closes an S(6) ring. In the crystal, the components are linked by N-H⋯N and weak C-H⋯N hydrogen bonds, which generate chains propagating in the [101] direction. Weak a ...[more]

Bis[1-(3-cyano-benz-yl)pyridinium] bis-(1,2-dicyano-ethene-1,2-dithiol-ato)nickelate(II).

Project description:In the ionic title complex, (C(13)H(11)N(2))(2)[Ni(C(4)N(2)S(2))(2)], the Ni(II) ion is located on an inversion centre so the asymmetric unit contains one-half [Ni(mnt)(2)](2-) dianion (mnt(2-) is maleonitrile-dithiolate) and one 1-(3-cyano-benz-yl)pyridinium cation ([CNBzPy](+)). The Ni(II) ion in the [Ni(mnt)(2)](2-) anion is coordinated by four S atoms of two mnt(2-) ligands, and exhibits square-planar coordination geometry. In the [CNBzPy](+) cation, the benzene and pyridine rings are twisted with respect to the C/C/N plane incorporating the methyl-ene C atom that links them. The crystal structure is stabilized by Coulombic inter-actions.

Bis{2-[2,5-bis-(pyridin-2-yl)-1H-imidazol-4-yl]pyridinium} tetra-cyanidoplatinate(II) tetra-hydrate.

Project description:The asymmetric unit of the title hydrated complex salt, (C18H14N5)2[Pt(CN)4]·4H2O, consists of one 2-[2,5-bis-(pyridin-2-yl)-1H-imidazol-4-yl]pyridinium cation, half a tetra-cyanidoplatinate(II) dianion, which is located about a crystallographic inversion center, and two water mol-ecules of crystallization. The Pt(II) atom has a square-planar coordination environment, with Pt-CCN distances of 1.992 (4) and 2.000 (4) Å. In the cation, there is an N-H⋯N hydrogen bond linking adjacent pyridinium and pyridine rings in positions 4 and 5. Despite this, the organic component is non-planar, as shown by the dihedral angles of 10.3 (2), 6.60 (19) and 15.66 (18)° between the planes of the central imidazole ring and the pyridine/pyridinium substituents in the 2-, 4- and 5-positions. In the crystal, cations and anions are linked via O-H⋯O, O-H⋯N and N-H⋯O hydrogen bonds, forming a three-dimensional network. Additional π-π, C-H⋯O and C-H⋯N contacts provide stabilization to the crystal lattice.

Crystal structure and Hirshfeld surface analysis of bis-(2,6-di-amino-pyridinium) tetra-chlorido-cobaltate(II).

Project description:In the title mol-ecular salt, (C5H8N3)2[CoCl4], the cations are protonated at their pyridine N atoms and the anion is an almost regular tetra-hedron. The crystal structure consists of alternating inorganic layers, built from tetra-chlorido-cobaltate anions, and organic layers formed by protonated cations of 2,6-di-amino-pyridinium. The crystal packing is governed by C/N-H⋯Cl hydrogen-bonding inter-actions between the organic and the inorganic ions and Cl⋯Cl inter-actions. Moreover, the cations show a π-π stacking inter-action [inter-centroid distance = 3.763 (2) Å]. The prevalence of these inter-actions is illustrated by an analysis of the three-dimensional Hirshfeld surface and by two-dimensional fingerprint plots.

1-(4-Cyano-benz-yl)-3,5-dimethyl-pyridinium bis-(benzene-1,2-dithiol-ato)nickelate(III).

Project description:The asymmetric unit of the title compound, (C(15)H(15)N(2))[Ni(C(6)H(4)S(2))(2)], contains half each of two independent centrosymmetric anions and a single cation in a general position. The Ni(III) ions are coordinated by four S atoms in a square-planar geometry. The anions exhibit two packing modes, viz. stacked along the a axis in a face-to-face fashion with an alternate arrangement of anions and cations, and stacked in a side-by-side fashion, forming ribbons parallel to (011).

Bis(4-chloro-pyridinium) tetra-chlorido-nickelate(II).

Project description:In the title compound, (C(5)H(5)ClN)(2)[NiCl(4)], the dianion lies on a twofold rotation axis. Two cations are linked to each anion by classical N-H⋯Cl hydrogen bonds, and short Cl⋯Cl contacts and Cl⋯π stacking inter-actions [with distances of 3.376 (2) and 3.684 (2) Å, respectively] extend this pattern into a chain. The [NiCl(4)](2-) anion shows significant deviation from ideal tetra-hedral geometry.

Project description:A new ion-pair complex, (C16H14N)2[Ni(C4N2S2)2] or (1-NaMePy)2[Ni(imnt)2], where 1-NaMePy is 1-(4-naphthyl-methyl-ene)pyridinium and imnt is 2,2-di-cyano-ethene-1,1-di-thiol-ate, was obtained by the direct reaction of NiCl2, K2imnt and (1-NaMePy)(+)Br(-) in H2O. The asymmetric unit contains a [1-NaMePy](+) cation and one half of an Ni(imnt)2 (2-) anion. The Ni(II) ion lies on an inversion centre and adopts a square-planar configuration with Ni-S bond lengths of 2.200?(1) and 2.216?(1)?Å. In the [1-NaMePy](+) cation, the naphthyl ringsystem and the pyridinium ring make a dihedral angle of 90.0?(2)°. In the crystal, C-H?N and C-H?Ni hydrogen bonds, as well as ?-? inter-actions between the chelate ring and the pyridinium ring [centroid-centroid distance = 3.675?(2)?Å] link the ions into a three-dimensional network.

4-Cyano-1-(4-nitro-benz-yl)pyridinium bis-(2-thioxo-1,3-dithiole-4,5-dithiol-ato-κS,S)nickelate(III).

Project description:In the title salt, (C(13)H(10)N(3)O(2))[Ni(C(3)S(5))(2)], the Ni(III) cation is S,S'-chelated by two 2-thioxo-1,3-dithiole-4,5-dithiol-ate anions in a distorted square-planar geometry. The complex anion is approximately planar with a maximum deviation of 0.097 (1) Å. In the 1-(4-nitro-benz-yl)-4-cyano-pyridinium cation, the pyridine ring is twisted at a dihedral angle of 73.84 (16)° with respect to the benzene ring. π-π stacking is observed between nearly parallel [dihedral angle = 4.71 (7)°] dithiole and benzene rings, the centroid-centroid distance being 3.791 (2) Å.

Crystal structure of bis-(2-amino-5-chloro-pyridinium) tetra-chlorido-cobaltate(II).

Project description:The title salt, (C5H6ClN2)2[CoCl4], was synthesized by slow evaporation of an aqueous solution at room temperature. The asymmetric unit consists of two essentially planar (C5H6ClN2)(+) cations [maximum deviations = 0.010?(3) and 0.014?(3)?Å] that are nearly perpendicular to each other [dihedral angle = 84.12?(7)°]. They are bonded through N-H?Cl hydrogen bonds to distorted [CoCl4](2-) tetra-hedra, leading to the formation of undulating layers parallel to (100). The structure is isotypic with the Zn analogue [Kefi et. al (2011). Acta Cryst. E67, m355-m356.].
