In the title compound, [Cu(CH(3)CN)(C(14)H(12)N(2))(2)](BF(4))(2)·2CH(3)CN, the Cu(II) atom shows a distorted CuN(5) square-pyramidal geometry with the acetonitrile N atom in an equatorial site, which differs substanti-ally from the distorted trigonal-bipyramidal arrangement usually observed for five-coordinate complexes of Cu(II) with two phenanthroline-type ligands and one other ligand. The B atom of one of the BF(4) (-) anions is disordered over two sites in a 0.825 (2):0.175 (2) ratio. In the crystal, C-H⋯F hydrogen bonds help to establish the packing.

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.

A new mixed-valence Cu/Cu three-dimensional coordination polymer, poly[[diaquabis[μ-2-(pyrazin-2-yl)quinoline-4-carboxylato]dicopper(I)copper(II)] bis(tetrafluoridoborate)], {[Cu(CHNO)(HO)](BF)}, was synthesized and characterized, with 2-(pyrazin-2-yl)quinoline-4-carboxylic acid being employed as a linker ligand. The ligand was isolated as its hydrochloride salt, 4-carboxy-2-(pyrazin-2-yl)quinolin-1-ium chloride dihydrate, CHNO·Cl·2HO. The compounds show luminescence at 550 nm for the ligand and at 565 nm for the polymer at 297 K.

Two new Co complexes, namely bis{N-[(6-bromopyridin-2-yl)methylidene]-2-[6-ethylamino-3-(ethyliminiumyl)-2,7-dimethyl-3H-xanthen-9-yl]benzene-1-carbohydrazonate}cobalt(II) bis(perchlorate)-dichloromethane-methanol (1/1/2), [Co(CHBrNO)](ClO)·CHCl·2CHOH or [Co(L)](ClO)·CHCl·2CHOH, (1), and the bis(tetrafluoridoborate) salt, [Co(CHBrNO)](BF)·CHCl·2CHOH or [Co(L)](BF)·CHCl·2CHOH, (2) (L is commonly 6-bromopyridine-2-carbaldehyde rhodamine 6G hydrazone), have been successfully constructed and characterized. The crystal structure analysis revealed that complexes (1) and (2) are mononuclear and have a CoNO distorted octahedral structure. The large π-conjugated xanthene moiety of the L ligand causes strong intermolecular π-π stacking interactions, yielding a supramolecular one-dimensional chain.

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.
