1,1'-Dimethyl-4,4'-bipyridinium bis-(tetra-fluorido-borate).

Acta Crystallogr Sect E Struct Rep Online

Published: December 2007

In the title compound, C(12)H(14)N(2) (2+)·2BF(4) (-), the cation has a centre of symmetry at the mid-point of the central C-C bond. π-π inter-actions, with a shortest atom-to-atom distance of 3.757 (4) Å, extend the crystal structure into a one-dimensional supra-molecular chain.

The reaction of [Cu(CHCN)](BF) with 1-methyl-1,3-imidazolidine-2-thione {SCH(NMe)NH}, under aerobic conditions at room temperature, yielded an unusual one-dimensional coordination polymer, namely, -poly[[[(1-meth-yl-1,3-imidazolidine-2-thione-κ)copper(I)]-μ-(1-methyl-1,3-imidazolidine-2-thione)-κ :-copper(I)-μ-[3,3'-(sulfanedi-yl)bis-(1-methyl-1,3-imidazolidine-2-thione)]-κ ,','':,''] bis-(tetra-fluorido-borate)], {[Cu(CHNS)(CHNS)](BF)} or [Cu(κ: -N-S-N- )(κ: -NH)(κ: -NH)] (BF) [ = SC H(NMe)NH] with sulfur-bridged {Cu S} central cores. The generated bis-(1-methyl-1,3-imidazolidinyl-2-thione) sulfide [{SCH(NMe)NSN(NMe)CHS; abbrev. -N-S-N- ] ligand, in combin-ation with 1-methyl-1,3-imidazolidine-2-thione ( -NH) ligands, construct this coordination polymer.

The crystal structure of a platinum(II) supra-molecular building block, [Pt(dbbpy)(NCCH)](BF) (dbbpy = 4,4'-di--butyl-2,2'-bi-pyridine, CHN) is an example of a rare head-to-head dimer, even with the bulky -butyl groups of the bi-pyridine. This packing motif still enables significant π-π inter-actions between two pyridyl groups, and may result from the close proximity of the tetra-fluorido-borate ions to the platinum(II) complexes, resulting in intra-molecular H⋯F distances between 2.156 and 2.

The mononuclear copper title complex {,,','-tetra-kis-[(6-methyl-pyridin-2-yl)meth-yl]ethane-1,2-di-amine-κ}copper(II) bis-(tetra-fluorido-borate), [Cu(CHN)](BF), is conveniently prepared from the reaction of Cu(BF)·6HO with ,,','-tetra-kis-[(6-methyl-pyridin-2-yl)meth-yl]ethane-1,2-di-amine (tmpen) in aceto-nitrile at room temperature in air. The complex shows a distorted octa-hedral environment around the Cu cation (site symmetry 2) and adopts the centrosymmetric space group 2/. The presence of the 6-methyl substituent hinders the approach of the pyridine group to the Cu core.

In the structure of the title salt, [Co(C6H6N2)2(H2O)2](BF4)2, the Co(II) atom is located on an inversion centre. The transition metal is in a slightly distorted octa-hedral coordination environment, defined by the cyano N atoms of four hex-3-enedi-nitrile ligands in equatorial positions and the O atoms of two water mol-ecules in axial positions. The bridging mode of the hex-3-enedi-nitrile ligands leads to the formation of cationic chains extending parallel to [1-10].
