Two-dimensional structure of poly[[[μ2-1,4-bis(pyridin-4-yl)butane]bis(μ4-pentanedioato)dicopper(II)] acetonitrile disolvate]

In the title compound, {[Cu2(μ4-C5H6O4)2(μ2-C14H16N2)]·2CH3CN}n, the Cu2dinuclear units are connected by glutartate ligands, forming one-dimensional double chains. These chains, are in turn bridged by 1,4-bis(pyridin-4-yl)butane ligands to form a two-dimensional layer structure parallel to (112). The carboxylate groups of the glutarate ligand bridge two copper(II) ions, forming a paddle-wheel-type Cu2(CO2)4dinuclear secondary building unit. A crystallographic inversion centre is located midway between two CuIIions, with a Cu...Cu distance of 2.639 (3) Å. The coordination geometry of the unique CuIIion is slightly disorted square pyramidal, formed by four equatorial carboxylate O atoms and an axial pyridyl N atom.

The title compound, [Cd3(C8H10O4)3(C12H9N3)2(H2O)2]nor [Cd3(chdc)3(4-PyBIm)2(H2O)2]n, was synthesized hydrothermally from the reaction of Cd(CH3COO)2·2H2O with 2-(pyridin-4-yl)-1H-benzimidazole (4-PyBIm) and cyclohexane-1,4-dicarboxylic acid (1,4-chdcH2). The asymmetric unit consists of one and a half CdIIcations, one 4-PyBIm ligand, one and a half 1,4-chdc2−ligands and one coordinated water molecule. The central CdIIcation, located on an inversion centre, is coordinated by six carboxylate O atoms from six 1,4-chdc2−ligands to complete an elongated octahedral coordination geometry. The two terminal rotationally symmetric CdIIcations each exhibits a distorted pentagonal–bipyramidal geometry, coordinated by one N atom from 4-PyBIm, five O atoms from three 1,4-chdc2−ligands and one O atom from an aqua ligand. The 1,4-chdc2−ligands possess two conformations,i.e.e,e-trans-chdc2−ande,a-cis-chdc2−. Thecis-1,4-chdc2−ligands bridge the CdIIcations to form a trinuclear {Cd3}-based chain along thebaxis, while thetrans-1,4-chdc2−ligands further link adjacent one-dimensional chains to construct an interesting two-dimensional network.

The title CdIIcompound, {[Cd2(C13H7NO4)2(H2O)4]·5H2O}n, was synthesized by the hydrothermal reaction of Cd(NO3)2·4H2O and 5-(pyridin-4-yl)isophthalic acid (H2L). The asymmetric unit contains two crystallographically independent CdIIcations, two deprotonatedL2−ligands, four coordinated water molecules and five isolated water molecules. One of the CdIIcations adopts a six-coordinate octahedral coordination geometry involving three O atoms from one bidentate chelating and one monodentate carboxylate group of two differentL2−ligands, one N atom of anotherL2−ligand and two coordinated water molecules. The second CdIIcation adopts a seven-coordinate pentagonal–bipyramidal coordination geometry involving four O atoms from two bidentate chelating carboxylate groups of two differentL2−ligands, one N atom of anotherL2−ligand and two coordinated water molecules. EachL2−ligand bridges three CdIIcations and, likewise, each CdIIcation connects to threeL2−ligands, giving rise to a two-dimensional graphite-like 63layer structure. These two-dimensional layers are further linked by O—H...O hydrogen-bonding interactions to form a three-dimensional supramolecular architecture. The photoluminescence properties of the title compound were also investigated.

The title compound, [Cu(C7H3NO4)(C5H6N2)(C3H7NO]n, is an amino-functionalized chiral metal–organic framework with (10,3)-atopology. It has been constructedviathe assembly of the achiral triconnected pyridine-3,5-dicarboxylate (3,5-PDC) building block and a triconnected CuIIatom. Each CuIIion is coordinated by two O atoms and one N atom, respectively, of three crystallographically independent 3,5-PDC ligands. The square-pyramidal (CuN2O3) coordination geometry of the CuIIion is completed by an N atom of a terminal 4-aminopyridine (4-APY) ligand and the O atom of a terminalN,N-dimethylformamide (DMF) ligand to give a triconnected `T'-shaped secondary building unit, which becomes trigonal in the resulting (10,3)-atopology. In the three-dimensional structure, weak N—H...O hydrogen bonds are observed in which the donor N—H groups are provided by the 4-APY ligands and the acceptor O atoms are provided by the non-coordinating carboxylate O atoms of the 3,5-PDC ligands.

One Pb atom is eight-coordinated, surrounded by seven carboxylate O atoms from five 5-IIP2−ligands and one O atom from the terminal methanol ligand. The other Pb atom is seven-coordinated in a hemidirected geometry, surrounded by seven carboxylate O atoms from five 5-IIP2−ligands. Both Pb atoms are connected by carboxylate groups to form a one-dimensional infinite rod along theaaxis; neighbouring rods are further linked by the aromatic rings of 5-IIP2−to generate the final three-dimensional structure with channels in theadirection. An O—H...O hydrogen bond between the methanol ligand and one of the carboxylate groups of a 5-IIP2−ligand stablizes the three-dimensional framework. Interestingly, a centrosymmetric rhombus-shaped I4unit is formed by four 5-IIP2−ligands, with I...I distances of 3.8841 (8) and 3.9204 (8) Å.

AgI-containing coordination complexes have attracted attention because of their photoluminescence properties and antimicrobial activities and, in principle, these properties depend on the nature of the structural topologies. A novel two-dimensional silver(I) complex with the anti-inflammatory diclofenac molecule, namely bis{μ-2-[2-(2,6-dichloroanilino)phenyl]acetato-κ3O,O′:O}bis(μ-2,5-dimethylpyrazine-κ2N:N′)silver(I), [Ag2(C14H10Cl2NO2)2(C6H8N2)]n, (I), has been synthesized and characterized by single-crystal X-ray diffraction, revealing that the AgIions are chelated by the carboxylate groups of the anionic 2-[2-(2,6-dichloroanilino)phenyl]acetate (dicl) ligand in a μ3-η1:η2coordination mode. Each dicl ligand links three AgIatoms to generate a one-dimensional infinite chain. Adjacent chains are connected through 2,5-dimethylpyrazine (dmpyz) ligands to form a two-dimensional layer structure parallel to the crystallographicbcplane. The layers are further connected by C—H...π interactions to generate a three-dimensional supramolecular structure. Additionally, the most striking feature is that the structure contains an intramolecular C—H ...Ag anagostic interaction. Furthermore, the title complex has been tested for itsin vitroantibacterial activity and is determined to be highly effective on the studied microorganisms.
