In the title polymeric complex, {[Cu(C14H14N2O6)(C3H4N2)2(H2O)]·2H2O}n, the CuIIcation, located on a twofold rotation axis, is coordinated by one water molecule and two imidazole molecules as well as two symmetry-related 3-([4-[(2-carboxylatoethyl)carbamoyl]phenyl]formamido)propanoate dianions (L2−) in an approximately square-pyramidal geometry. The coordinating water molecule is located on a twofold rotation axis while theL2−anion sits about an inversion center. TheL2−anions bridge the CuIIcations, forming polymeric chains propagating along the [101] direction. In the crystal, O—H...O, N—H...O hydrogen bonds and weak C—H...π interaction link the polymeric chains and the solvent water molecules into a three-dimensional supramolecular architecture.

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.

The Mean

Treatment ofN,N-bis(pyridin-4-ylmethyl)cyclohexane-1,4-diamine with hydrochloric acid in ethanol led to the formation of the title salt, C18H26N42+·2Cl−·2H2O, which lies about a crystallographic inversion center at the center of the cyclohexyl ring. The asymmetric unit therefore comprises one half of theN,N-bis(pyridin-4-ylmethyl)cyclohexane-1,4-diammonium dication, a chloride anion, and a solvent water molecule. In the dication, the twotrans-(4-pyridine)–CH2–NH2– moieties occupy equatorial sites at the 1- and 4-positions of the central cyclohexyl ring, which is in a chair conformation. The terminal pyridine ring is tilted by 27.98 (5)° with respect to the mean plane of the central cyclohexyl moiety (r.m.s. deviation = 0.2379 Å). In the crystal, dications, anions, and solvent water molecules are connectedviaN/C/O—H...Cl and N—H...O hydrogen bonds together with C—H...π interactions, forming a three-dimensional network.
