In the title compound, [CdNi(C9H8N2)2(CN)4] n , the Cd and Ni atoms both lie on centres of inversion in space group P21/c. The Cd atom is coordinated by two bidentate quinolin-8-amine ligands and by the N atoms of two cyano ligands, while the square planar Ni atom is coordinated by the C atoms of four cyano ligands. These units form a one-dimensional coordination polymer containing an (–NC—Ni—CN—Cd–) n backbone, and the coordination polymer chains are linked into a three-dimensional array by a combination of N—H...N and C—H...N hydrogen bonds, augmented by a π–π stacking interaction.

The structure of the title compound, [Cd2(C8H4O4)Cl2(C6H15NO3)]n, consists of one-dimensional chains in which each centrosymmetric tetranuclear Cd4Cl4O2cluster is terminated by two chelating triethanolamine (teaH3) ligands but linked to two adjacent clusters through four bridging benzene-1,4-dicarboxylate (bdc) ligands. The tetranuclear Cd4Cl4O2clusters are held togetherviabridging Cl and O atoms. Three directional hydrogen bonds from the multi-podal hydroxy groups of the teaH3ligand stabilize and extend the one-dimensional chains into a three-dimensional framework. All three hydroxy groups of the teaH3ligand form hydrogen bonds, illustrating the fact that the teaH3ligand can serve as an excellent hydrogen-bond donor.

In the title compound, (C6H8N4)[AuCl4]Cl, the 4,4′-bi(1H-pyrazol-2-ium) dication, denoted [H2bpz]2+, is situated across a centre of inversion, the [AuCl4]−anion lies across a twofold axis passing through Cl—Au—Cl, and the Cl−anion resides on a twofold axis. Conventional N—H...Cl hydrogen bonding [N...Cl = 3.109 (3) and 3.127 (3) Å, and N—H...Cl = 151 and 155°] between [H2bpz]2+cations (square-planar node) and chloride anions (tetrahedral node), as complementary donors and acceptors of four hydrogen bonds, leads to a three-dimensional binodal four-connected framework with cooperite topology (three-letter notation pts). The framework contains channels along thecaxis housing one-dimensional stacks of square-planar [AuCl4]−anions [Au—Cl = 2.2895 (10)–2.2903 (16) Å; interanion Au...Cl contact = 3.489 (2) Å], which are excluded from primary hydrogen bonding with the [H2bpz]2+tectons.

One of the two dicyanamide ligands is a terminal ligand, but the other one acts as a μ1,5-bridging ligand between pairs of CuIIcentres, so generating a one-dimensional coordination polymer. A combination of N—H...N and C—H...N hydrogen bonds, augmented by π–π stacking interactions, links the coordination polymer chains into a bilayer structure. Comparisons are made with some related CuIIcomplexes containing dca ligands and heteroaromatic co-ligands.

In the title one-dimensional coordination polymer, [Mn(NCS)3(C10H16N3)]n, the MnIIatom is coordinated by anN,N′-bidentate Schiff base and four thiocyanate ligands in a distorted octahedral N5S geometry. Bridging thiocyanate ligands interconnect adjacent [Mn(NCS)2(C10H16N3)] units, giving rise to helical chains extending along thebaxis. The chains are further linked through N—H...S hydrogen bonds, leading to a three-dimensional supramolecular network.

4-Hydroxypyridine-2,6-dicarboxylic acid (chelidamic acid, hypydc[H]H2) reacts with MnCl2·2H2O in the presence of piperazine in water to afford the title complex, {[Mn3(C7H2NO5)2(H2O)8]·3H2O}nor {[Mn3(hypydc)2(H2O)8]·3H2O}n. This compound is a one-dimensional coordination polymer, with the twofold symmetric repeat unit containing three metal centres. Two different coordination geometries are observed for the two independent MnIImetal centres,viz.a distorted pentagonal bipyramid and a distorted octahedron. The 4-oxidopyridine-2,6-dicarboxylate anions and two of the water molecules act as bridging ligands. The zigzag-like geometry of the coordination polymer is stabilized by hydrogen bonds. O—H...O and C—H...O hydrogen bonds and water clusters consolidate the three-dimensional network structure.

The rigid organic ligand (pyridine-3,5-diyl)diphosphonic acid has been used to create the title novel three-dimensional coordination polymer, [Ca(C5H6NO6P2)2(H2O)]n. The six-coordinate calcium ion is in a distorted octahedral environment, formed by five phosphonate O atoms from five different (pyridin-1-ium-3,5-diyl)diphosphonate ligands, two of which are unique, and one water O atom. Two crystallographically independent acid monoanions,L1 andL2, serve to link metal centres using two different coordination modes,viz.η2μ2and η3μ3, respectively. The latter ligand,L2, forms a strongly undulated two-dimensional framework parallel to the crystallographicbcplane, whereas the former ligand,L1, is utilized in the formation of one-dimensional helical chains in the [010] direction. The two sublattices ofL1 andL2 interweave at the Ca2+ions to form a three-dimensional framework. In addition, multiple O—H...O and N—H...O hydrogen bonds stabilize the three-dimensional coordination network. Topologically, the three-dimensional framework can be simplified as a very unusual (2,3,5)-connected three-nodal net represented by the Schläfli symbol (4·82)(4·88·10)(8).
