A novel terbium-tetracarboxylate framework with the 5,5’-(diazene-1,2-iyl)diisophthalic acid (H4abtc) ligand, formulated as [Tb(Habtc)(DMSO)(H2O)2]n (ZTU-5), has been synthesized and structurally characterized. ZTU-5 features a 2D-layered structure constructed by the binuclear terbium secondary building units (SBUs) and abtc4– ligand, which can be further expanded into a 3D-supramolecular framework by the hydrogen bond interactions. In addition, the magnetic and fluorescence properties of ZTU-5 are investigated and ZTU-5 exhibits highly selective and sensitive detection of nitrofurazone (NZF).

[μ-N,N′-Bis(pyridin-3-yl)benzene-1,4-dicarboxamide-<!?show [forcelb]><!?tlsb=0.12pt>1:2κ2N:N′]bis{[N,N′-bis(pyridin-3-yl)benzene-1,4-dicarboxamide-κN]diiodidomercury(II)}, [Hg2I4(C18H14N4O2)3], is an S-shaped dinuclear molecule, composed of two HgI2units and threeN,N′-bis(pyridin-3-yl)benzene-1,4-dicarboxamide (L) ligands. The centralLligand is centrosymmetric and coordinated to two HgIIcationsviatwo pyridine N atoms, in asyn–synconformation. The two terminalLligands are monodentate, with one uncoordinated pyridine N atom, and each adopts asyn–anticonformation. The HgI2units show highly distorted tetrahedral (sawhorse) geometry, as the HgIIcentres lie only 0.34 (2) or 0.32 (2) Å from the planes defined by the I and pyridine N atoms. Supramolecular interactions, thermal stability and solid-state luminescence properties were also measured.

The title complex, {[Cd(C2O4)(C2H3N3S)(H2O)]·H2O}n, has a two-dimensional metal–organic framework, with the CdIIcation coordinated by three oxalate ligands, a 1H-1,2,4-triazole-5(4H)-thione (H2trzS) ligand and a water molecule. The CdO6S and oxalate units form an extended two-dimensional layered structure, with the terminal H2trzS ligands bonded to the CdIIsites through the thione S atoms. Hydrogen-bond interactions exist between adjacent layers.

The reaction of 2-aminoterephthalic acid and 1,10-phenanthroline with Cd(NO[Formula: see text][Formula: see text]4H2O under solvothermal conditions leads to the formation of [Cd(2-aip)(phen)][Formula: see text][Formula: see text][Formula: see text]0.5C2H5OH ( 1). In the compound, dimetallic cluster [Cd2(COO)4] exists and is linked by 2-aip ligands to stretch into a 2D flat layer. These layers are lined parallel to each other via N–H[Formula: see text]OCO hydrogen bond interactions, generating a 3D supramolecular architecture. The sensing property has been investigated. The experimental results show that the compound can be used as a luminescent probe to detect Co[Formula: see text] and organic small molecules acetone.

Distorted Octahedral

The structure of the centrosymmetric title complex, [Cu(C5H9O2)2(C6H7NO)2], has the CuIIatom on a centre of inversion. The CuIIatom is six-coordinate with a distorted octahedral geometry, defined by the N and O atoms of the chelating 2-(2-hydroxymethyl)pyridine ligands and two carboxylate O atoms from two monodentate pivalate ions. The crystal packing is stabilized by intermolecular C—H...O and intramolecular O—H...O hydrogen-bond interactions.

A further example of using a covalent-bond-forming reaction to alter supramolecular assembly by modification of hydrogen-bonding possibilities is presented. This concept was introduced by Lemmerer, Bernstein & Kahlenberg [CrystEngComm(2011),13, 55–59]. The title structure, C9H11N3O·C7H6O4, which consists of a reacted niazid molecule,viz.N′-(propan-2-ylidene)nicotinohydrazide, and 2,4-dihydroxybenzoic acid, was solved from powder diffraction data using simulated annealing. The results further demonstrate the relevance and utility of powder diffraction as an analytical tool in the study of cocrystals and their hydrogen-bond interactions.
