The bromo-substituted aromatic dicarboxylic acid 5-amino-2,4,6-tribromoisophthalic acid (H2ATBIP) was used to assemble with CdII ions in the presence of the N-donor flexible bipyridyl ligands 3,3′-(diazene-1,2-diyl)dipyridine (mzpy) and 1,3-bis(pyridin-3-ylmethyl)urea (3bpmu), leading to the formation of two chain coordination polymers by adopting solution methods, namely, catena-poly[[[triaqua(5-amino-2,4,6-tribromoisophthalato-κO)cadmium(II)]-μ-3,3′-(diazene-1,2-diyl)dipyridine-κ2 N 1:N 1′] dihydrate], {[Cd(C8H2Br3NO4)(C10H8N4)(H2O)3]·2H2O} n or {[Cd(ATBIP)(mzpy)(H2O)3]·2H2O} n , (1), and catena-poly[[[tetraaquacadmium(II)]-μ-1,3-bis(pyridin-3-ylmethyl)urea-κ2 N 1:N 1′-[diaquabis(5-amino-2,4,6-tribromoisophthalato-κO)cadmium(II)]-μ-1,3-bis(pyridin-3-ylmethyl)urea-κ2 N 1:N 1′] octahydrate], {[Cd(C8H2Br3NO4)(C12H12N4O)(H2O)3]·4H2O} n or {[Cd(ATBIP)(3bpmu)(H2O)3]·4H2O} n , (2). Both complexes were characterized by FT–IR spectroscopic analysis, thermogravimetric analysis (TGA), solid-state diffuse reflectance UV–Vis spectroscopic analysis, and single-crystal and powder X-ray diffraction analysis (PXRD). The mzpy and 3bpmu ligands bridge the CdII metal centres in (1) and (2) into one-dimensional chains, and the ATBIP2− ligands show a monodentate coordination to the CdII centres in both coordination polymers. A discrete water tetramer exists in (1). Within the chains of (1) and (2), there are halogen bonds between adjacent ATBIP2− and mzpy or 3bpmu ligands, as well as hydrogen bonds between the ATBIP2− ligands and the coordinated water molecules. With the aid of weak interactions, the structures of (1) and (2) are further extended into three-dimensional supramolecular networks. An analysis of the solid-state diffuse reflectance UV–Vis spectra of (1) and (2) indicates that a wide indirect band gap exists in both complexes. Complexes (1) and (2) exhibit irreversible and reversible dehydration–rehydration behaviours, respectively, and the solid-state fluorescence properties of both complexes have been studied.

The structure and solid state luminescence properties of a homometallic heterotrinuclear [Eu(μO)5(OH2)3][Eu(DOTA)(H2O)]2Cl crystal was determined and was found to have two sites: a free europium(III) ion and a [Eu(DOTA)(H2O)]- complex. The trinuclear compound crystallizes in a laminar structure in triclinic space group P. The crystal structure was determined using complex data treatment due to non-merohedric twinning. Experimental data sets were recorded with large redundancy and separated according to scattering domain in order to obtain a reliable structure, which revealed the configuration of the europium(III) sites. In first site, the europium(III) 1,4,7,10-tetrazacyclododecane-1,4,7,10-tetraacetate (Eu.DOTA) complex was found to adopt a capped twisted square antiprismatic (cTSAP) conformation, where a capping water molecule increased the coordination number of the europium(III) site to nine (CN = 9). In the second site, the cationic europium(III) ion was found to be coordinated by three water molecules and five oxy groups from neighboring [Eu(DOTA)(H2O)]- complexes. The coordination geometry of this site was found to be a compressed square antiprism (SAP), and the coordination number of the europium(III) ion was found to be eight (CN = 8). A large increase in rate constant of luminescence was observed for Eu(III) in [Eu(DOTA)(H2O)]- in solid state luminescence spectroscopy measurements compared to in solution, which lead to investigations of single-crystals in deuterated media to exclude additional effects of quenching. We conclude that the most probable cause of the decrease in observed luminescence lifetimes is the high asymmetry of the coordination environment of [Eu(DOTA)(D2O)]- in the [Eu(μO)5(OD2)3][Eu(DOTA)(D2O)]2Cl crystals<br>

A new square-shaped Zn(II) complex, namely, [Zn4(L)4(phen)4]?6H2O (1) (L = 2-hydroxynicotinate and phen = 1,10- phenanthroline), has been synthesized under hydrothermal condition. The crystal of 1 belongs to triclinic, space group P -1 with a = 10.773(2) ?, b = 12.641(3) ?, c = 13.573(3) ?, ? = 107.44(3)?, ? = 102.66(3)?, ? = 93.89(3)?, C72H56N12O18Zn4, Mr = 1638.77, V = 1702.8(6) ?3 , Z = 1, Dc = 1.598 g/cm3 , S = 1.045, ?(MoK?) = 1.475 mm-1 , F(000) = 836, R = 0.0472 and wR = 0.0919. In 1, four L ligands bridge four Zn(II) atoms to form a square-shaped structure, where four phen ligands are respectively located on four corners of the square. The ?-? stacking interactions extend the adjacent squares into a 1D supramolecular chain. The thermal behavior of 1 has been characterized. Moreover, its solid state luminescence property has been studied at room temperature.

Two new polymeric MnII complexes, {[Mn(1,2-BDC-F4)(H2O)3](EtOH)}n (1) and [Mn(1,2- BDC-F4)(H2O)2(DMF)]n (2), have been prepared from the reaction of MnII acetate with 3,4,5,6- tetrafluoro-benzene-1,2-dicarboxylic acid (1,2-H2BDC-F4) using different solvents, and characterized by elemental analysis, IR spectroscopy, thermogravimetric (TG) analysis, and single-crystal Xray structure analysis. Both complexes crystallize in the triclinic space group P1̄ and have similar one-dimensional double chain structures, consisting of a unique arrangement of 8-membered and 14- membered rings. The effects of solvent as ligand and/or guest on the self-assembly processes of the supramolecular networks and on their photoluminescence properties in the solid state are discussed.
