The synthesis of the salt 3 and metallo-organic framework (MOF) [{(4,4(')-bipy)CoBr(2)}(n)] 4 by a range of solid state (mechanochemical and thermochemical) and solution methods is reported; they are isostructural with their respective chloride analogues 1 and 2. 3 and 4 can be interconverted by means of HBr elimination and absorption. Single phases of controlled composition and general formula...

The synthesis and characterisation of a series of dinuclear ruthenium and osmium polypyridyl metal complexes based on the bridging ligands [5-(5'-bipyridin-2',2''-yl)-3-(pyridin-2-yl)]-1,2,4-triazole (Hpytr-bipy), 2,2'-bis(pyridin-2''yl)-5,5'-bis(pyridin-3''-yl) (bipy-bipy) and 5,5'-bis(pyridin-2''-yl)-3,3'-bis(1,2,4-triazole) (Hpytr-Hpytr) are reported. The dinuclear complexes have been synthe...

Using ligands based on either an acetylacetonate or a dipyrrin moiety appended with pyridyl groups, a series of novel heteroleptic copper(II) and cobalt(III) complexes combining both chelate units such as (acacpy(2))Cu(dpm-py) and (acacpy(2))Co(dpm-py)(2) (acacpy(2) = 1,3-bis(4-pyridyl)-1,3-propanedionate; dpm-py = 5-(4-pyridyl)dipyrrin) have been prepared and fully characterized. These two com...

Purpose: To investigate the antimicrobial, antibiofilm, and cytotoxicity properties of methallyl substituted benzimidazolium-based, silver-bound N-heterocyclic carbene (Ag(I)-NHC) complexes, with respect to their potential act as antimicrobial agents.Methods: The four synthesis characterization which were carried out previously, investigated. tested using broth microdilution method, while antib...

Eleven iron(II) 1D coordination polymers with the general formula [FeLeq(Lax)]· solvent were synthesised and characterised, where Leq = {diethyl (E,E)-2,2′-[1,2-phenylbis(iminomethylidyne)]bis[3-oxobutanoate] (2-)-N,N′,O,O′} (L1) and {3,3′-[1,2-phenylbis(iminomethylidyne)]bis[pentane-2,4-dione] (2-)-N,N′,O,O′} (L2); Lax = 4,4′-bipyridine (bipy), 1,2-bis(4-pyridyl)ethane (bpea) and 1,3-bis(4-pyr...

In the title compound, {[Ni(C(10)H(8)N(2))(H(2)O)(4)](C(12)H(8)O(4))}(n), the Ni(II), 4,4'-bipyridyl (bipy) and 3,3'-(p-phenyl-ene)diacrylate (L(2-)) moieties are situated on inversion centres. The bipy ligands bridge Ni(II) ions into positively charged polymeric chains along [101]. The Ni(II) atom is coordinated by two N atoms from two bipy ligands and four water mol-ecules in a distorted octa...

Heterobimetallic complexes [Cu(N C-Cy-C N)2][Au(C6F5)2]·0.5 Toluene (1) and [Cu(N C-CyC N)2][Au(C6F5)2]·CH2Cl2 (2) and [AuCu(C6F5)2(N C-Cy-C N)2]·CH2Cl2 (3) (with the same stoichiometry but different structure) have been synthesized and the crystal structure of complex 2·CH2Cl2 has been characterized through X-ray diffraction studies. The structure shows a cationic [Cu(N C-Cy-C N)2] + polymer t...

A bimetallic pillared-layer coordination framework {[Mn(3)(bipy)(3)(H(2)O)(4)][Cr(CN)(6)](2)·2(bipy)·4(H(2)O)}(n) has been constructed using a cyanometallate anion ([Cr(CN)(6)](3-)) and an organic linker (4,4'-bipyridyl) that provides high heat of hydrogen adsorption (∼11.5 kJ mol(-1)) and shows guest dependent magnetic modulation.

The first soft donor adducts of TiF(4), [TiF(4)(diphosphine)] (diphosphine = o-C(6)H(4)(PMe(2))(2), R(2)P(CH(2))(2)PR(2), R = Me or Et) have been prepared from [TiF(4)(MeCN)(2)] and the diphosphines in rigorously anhydrous CH(2)Cl(2), as extremely moisture sensitive yellow solids, and characterised by multinuclear NMR ((1)H, (31)P, (19)F), IR and UV/vis spectroscopy. The crystal structure of [T...

The reaction of anhydrous lanthanide chlorides together with 4,4'-bipyridine yields the MOFs 2∞[Ln2Cl6(bipy)3]·2bipy, with Ln = Pr - Yb, bipy = 4,4'-bipyridine, and 3∞[La2Cl6(bipy)5]·4bipy. Post-synthetic thermal treatment in combination with different vacuum conditions was successfully used to shape the porosity of the MOFs. In addition to the MOFs microporosity, a tuneable mesoporosity can be...
