The central copper(II) atom of the title salt, {[Cu(CF3SO3)(CH3CN)2(C12H12N2O2)](CF3SO3)} n or [[Cu(CH3CN)2(diOMe-bpy)(CF3SO3)](CF3SO3)] n where diOMe-bpy is 4,4′-dimethoxy-2,2′-bipyridine, C12H12N2O2, is sixfold coordinated by the N atoms of the chelating bipyridine ligand, the N atoms of two acetonitrile molecules, and two trifluoromethanesulfonate O atoms in a tetragonally distorted octahedral shape. The formation of polymeric chains [Cu(CH3CN)2(diOMe-bpy)(CF3SO3)]+ n leaves voids for the non-coordinating trifluoromethanesulfonate anions that interact with the complex through weak hydrogen bonds. The presence of weakly coordinating ligands like acetonitrile and trifluoromethanesulfonate makes the title compound a convenient starting material for the synthesis of novel metal–organic frameworks.

In the title compound [Fe(bpe)(Hbpe)Au(CN)2][Au(CN)2]2·bpe·2H2O} n [where bpe = 1,2-bis(pyridin-4-yl)ethene, C12H10N2], the FeII ion is coordinated in a distorted octahedral [FeN4O2] environment by two dicyanoaurate anions, two water molecules and two partially protonated 1,2-di(4-pyridyl)ethylene molecules. Dicyanoaurate anions bridge the FeII cations, forming infinite chains, which propagate along the a-axis direction. The chains are connected via aurophilic interactions with two non-coordinated dicyanoaurate anions for each FeII ion. The polymeric chains interact with each other via π–π stacking between the guest bpe molecules and multiple hydrogen bonds.

In the crystal, O—H...O and weak C—H...Cl hydrogen bonds are observed.

The asymmetric unit of the title compound, [Mn(C6H6N4)2(H2O)2](C8H4O4), contains one-half each of the centrosymmetric cation and anion. The MnII atom is coordinated by four N atoms [Mn—N = 2.2168 (14) and 2.2407 (14) Å] from two 2,2′-biimidazole ligands and two water molecules [Mn—O = 2.2521 (14) Å] in a distorted octahedral geometry. Intermolecular N—H...O and O—H...O hydrogen bonds consolidate the crystal packing, which also exhibits π–π interactions between five-membered rings, with a centroid–centroid distance of 3.409 (2) Å.

In the title polymeric complex, {[Fe(C12H10N2)2(H2O)4](CH3C6H4SO3)2·2CH3OH}n, the FeIIcation, located on an inversion centre, is coordinated by four water molecules in the equatorial positions and two 1,2-bis(pyridin-4-yl)ethene molecules in the axial positions. This results in a distorted octahedral geometry for the [N2O4] coordination polyhedron. The 1,2-bis(pyridin-4-yl)ethene molecules bridge the FeIIcations, forming polymeric chains running along thea-axis direction. Stabilization of the crystal structure is provided by O—H...O hydrogen bonds; these are formed by coordinated water molecules as donors towards the O atoms of the methanol molecules and tosylate anions as acceptors of protons, leading to the formation of a three-dimensional supramolecular network. Weak C—H...O hydrogen bonds are also observed in the crystal.
