1-(2,4-Dichloro-benz-yl)pyridinium bis-(2-sulfanyl-idene-1,3-dithiole-4,5-dithiol-ato-?S,S')nickelate(III).

ABSTRACT: In the title compound, (C(12)H(10)Cl(2)N)[Ni(C(3)S(5))(2)], the Ni(III) atom is chelated by two bidentate 2-sulfanyl-idene-1,3-dithiole-4,5-dithiol-ate (dmit) dianions and shows a distorted square-planar geometry. The two dmit ligands are twisted with respect to each other by 3.21?(2)°. In the cation, the two aromatic groups linked by the methyl-ene bridging group form a dihedral angle of 68.09?(2)°. S?S [3.6212?(11) and 3.5573?(9)?Å] and Ni?S [3.566?(2)Å] inter-actions influence the arrangement of the anions in the crystal.

1-(2-Fluoro-benz-yl)quinolinium bis-(2-sulfanylidene-1,3-dithiole-4,5-dithiol-ato-κS,S')nickelate(III).

Project description:The crystal structure of the title compound, (C(16)H(13)FN)[Ni(C(3)S(5))(2)], consists of Ni(III) complex anions and 1-(2-fluoro-benz-yl)quinolinium (fbq) cations. In the complex anion, the Ni(III) cation is chelated by two 2-sulfanylidene-1,3-dithiole-4,5-dithiol-ate (dmit) dianions in a distorted square-planar geometry; the two dmit mean planes are twisted with respect to each other at a dihedral angle of 8.44 (3)°. In the fbq cation, the dihedral angle between the benzene ring and the quinoline ring system is 80.57 (14)°. The centroid-centroid distance of 3.860 (5) Å between benzene rings indicates π-π stacking between adjacent fbq cations. The distance of 3.4958 (18) Å between the S atom and the centroid of the pyridine ring suggests the existence of a lone-pair-aromatic inter-action between the anion and the cation. A short S⋯S contact [3.387 (2) Å] is also observed in the crystal structure.
