Crystal structure of bis-[1-(4-bromo-benz-yl)pyridinium] bis-(1,2-di-cyano-ethene-1,2-di-thiol-ato-?(2) S,S')nickelate(II).

ABSTRACT: The asymmetric unit of the title salt, (C12H11BrN)2[Ni(C4N2S2)2], consists of one 1-(4-bromo-benz-yl)pyridinium cation and one half of a complex [Ni(mnt)2](2-) (mnt(2-) is the maleo-nitrile-dithiol-ate dianion). The Ni(2+) ion is located on an inversion centre and is coordinated by four S atoms from two mnt(2-) ligands, exhibiting a square-planar coordination environment. In the cation, the planes of the pyridinium and benzene rings make a dihedral angle of 69.86?(19)°. The cations and anions are alternately arranged in layers parallel to (001) and are held together by non-classical C-H?N hydrogen bonds.

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(1-ethyl-4,4'-bipyridin-1-ium) bis-(1,2-di-cyano-ethene-1,2-di-thiol-ato-?(2) S,S')nickelate(II).

Project description:In the anion of the title compound, (C12H13N2)[Ni(C4N2S2)2], the Ni(II) atom is coordinated by four S atoms from two 1,2-di-cyano-ethene-1,2-di-thiol-ate (mnt) ligands in a suqare-planar geometry. Weak C-H?N and C-H?S hydrogen bonds between the 1-ethyl-4,4'-bipyridin-1-ium cations and mnt anions and weak ?-? inter-actions between the pyridine rings of the cations [centroid-centroid distances = 3.808?(3) and 3.972?(3)?Å] lead to a two-dimensional network parallel to (010).

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.
