In the title one-dimensional coordination polymer, [Cu(SiF6)(C3H4N2)4]n, the CuIIatom is coordinated by two hexafluoridosilicate F atoms and four pyrazole N atoms in a distortedtrans-CuF2N4octahedral environment. The dihedral angle between the planes of the pyrazlole rings in the asymmetric unit is 74.4 (3)°. The hexafluoridosilicate dianion acts as a bridging ligand, connecting the CuIIatoms into a [1-10] chain. The Cu and Si atoms lie on special positions with 2/msite symmetry. In the crystal, intrachain N—H...F hydrogen bonds occur and weak C—H...F interactions link the chains.

The azide anion is a short bridging ligand that has been used extensively to construct magnetic coordination polymers, and fundamental magneto-structural correlations have been substantiated by theoretical calculations. The copper(II) coordination polymer poly[bis(μ-azido-κ2N1:N1)(μ4-homophthalato-κ4O:O′:O′′:O′′′)bis(pyridine-κN)dicopper(II)], [Cu2(C9H6O4)(N3)2(C5H5N)2]n, was synthesized from homophthalic acid (2-carboxyphenylacetic acid), pyridine and azide (N3−) by a hydrothermal reaction. Single-crystal structure analysis indicated that it features a one-dimensional chain structure which is comprised of (μ1,1-N3−)(μ-syn–syn-COO−)2- and (μ1,1-N3−)2-bridged tetranuclear CuIIunits. Magnetic measurements revealed that the compound exhibits dominant antiferromagnetic behaviour.

Reactions of 1,10-phenanthroline (phen) and 2-(3,4-dichlorophenyl)acetic acid (dcaH) with Mn (CO3) (M = LiI, NaI and MgII; n = 1 and 2) in MeOH yield the mononuclear lithium complex aqua[2-(3,4-dichlorophenyl)acetato-κO](1,10-phenanthroline-κ2 N,N′)lithium(I), [Li(C8H5Cl2O2)(C12H8N2)(H2O)] or [Li(dca)(phen)(H2O)] (1), the dinuclear sodium complex di-μ-aqua-bis{[2-(3,4-dichlorophenyl)acetato-κO](1,10-phenanthroline-κ2 N,N′)sodium(I)}, [Na2(C8H5Cl2O2)2(C12H8N2)2(H2O)2] or [Na2(dca)2(phen)2(H2O)2] (2), and the one-dimensional chain magnesium complex catena-poly[[[diaqua(1,10-phenanthroline-κ2 N,N′)magnesium]-μ-2-(3,4-dichlorophenyl)acetato-κ2 O:O′] 2-(3,4-dichlorophenyl)acetate monohydrate], {[Mg(C8H5Cl2O2)(C12H8N2)(H2O)2](C8H5Cl2O2)·H2O} n or {[Mg(dca)(phen)(H2O)2](dca)·H2O} n (3). In these complexes, phen binds via an N,N′-chelate pocket, while the deprotonated dca− ligands coordinate either in a monodentate (in 1 and 2) or bidentate (in 3) fashion. The remaining coordination sites around the metal ions are occupied by water molecules in all three complexes. Complex 1 crystallizes in the triclinic space group P\overline{1} with one molecule in the asymmetric unit. The Li+ ion adopts a four-coordinated distorted seesaw geometry comprising an [N2O2] donor set. Complex 2 crystallizes in the triclinic space group P\overline{1} with half a molecule in the asymmetric unit, in which the Na+ ion adopts a five-coordinated distorted spherical square-pyramidal geometry, with an [N2O3] donor set. Complex 3 crystallizes in the orthorhombic space group P212121, with one Mg2+ ion, one phen ligand, two dca− ligands and three water molecules in the asymmetric unit. Both dcaH ligands are deprotonated, however, one dca− anion is not coordinated, whereas the second dca− anion coordinates in a bidentate fashion bridging two Mg2+ ions, resulting in a one-dimensional chain structure for 3. The Mg2+ ion adopts a distorted octahedral geometry, with an [N2O4] donor set. Complexes 1–3 were evaluated against urease and α-glucosidase enzymes for their inhibition potential and were found to be inactive.

Crystals of the title compound, [HgI2(C18H14N4O2)] n , were obtained by the reaction of HgI2 and p-phenylene-bis(pyridine-3-carboxamide) in DMF. The asymmetric unit is composed of only half of the formula unit; the mercury atom lies on a crystallographic twofold rotation axis, and there is an inversion centre at the centre of the benzene ring. Each HgII atom is coordinated by two I atoms and two N atoms from two p-phenylene-bis(pyridine-3-carboxamide) (bpfb) ligands, in a distorted tetrahetral geometry. Bpfb acts as a bifunctional bridging ligand, linking HgII atoms into a one-dimensional chain. Hydrogen-bonding interactions between the O atom and the H atoms of bpfb ligands result in a two-dimensional supramolecular network.
