The electronic properties of cation radical salts derived from organometallic mixed-ligand complexes [(ppy)Au(S-S)](ppy- = C-dehydro-2-phenylpyridine(-); S-S(2-) = dithiolene ligand) with Au(III)-C sigma-bond were investigated. A 2:1 salt complex [(ppy)Au(C8H4S8)]2[PF6] (C8H4S8(2-) = 2-((4,5-ethylenedithio)-1,3-dithiole-2-ylidene)-1,3-dithiole-4,5-dithiolate(2-)) exhibited semiconductive behavi...
The reaction of [Ru(L)2(H2biim)](ClO4)2 [L1 = 2,2¢-bipyridine (bpy) or L2 = 2-(phenylazo)pyridine (pap) and H2biim = 2,2¢-biimidazole] with Au(tht)Cl (tht = tetrahydrothiophene) in presence of base in methanol produced a terametallic cationic complex [{Ru(L)2(biim)}<s...
An increasing interest has been sustained in the chemistry of metal-organic frameworks owing to their unique unusual properties and potential biological activities. Mono-substituted derivatives of benzoic acid such as hydroxybenzoic and nitrobenzoic acids demonstrate a low antimicrobial and moderate growth stimulating actions. Ethanolamines also show the same types of the biological action. In ...
Organometallic complexes offer potential for design as anticancer drugs. A quantitativemodel that discriminates anticancer compounds from the inactive ones in a training series wasEquilibrium of the reaction of molybdenum (VI) with l-histidine have been studiedin aqueous solutions at pH range of 4-8, using spectrophotometry and optical rotationmethods at constant ionic strength of 0.15 mol.lit-...
some new water-soluble schiff base complexes of na2[m(5-so3-1,2-salophen)].nh2o; (5-so3-1,2-salophen = n,n’-bis(5-sulphosalicyliden)-1,2-phenylendiamine); na2[m(5-so3-2,3-salpyr)(h2o)n].2h2o; (5-so3-2,3-salpyr = n,n’-bis(5-sulphosalicyliden)-2,3-diaminopyridine); and na2[m(5-so3-3,4-salbenz)(h2o)n].nh2o; (5-so3-3,4-salbenz = n,n’-bis(5-sulphosalicyliden)-3,4-diaminobenzophenon); where m = cu, n...
A novel mixed-ligand copper(II) complex with N-(p-methoxybenzyl)-iminodiacetato(2)) ligand (MOBIDA) and adenine (AdeH) of formula 1⁄2CuðMOBIDAÞðAdeHÞðH2OÞ H2O has been obtained. Its crystal structure reveals the selective formation of a rare Cu– N3(AdeH) bond, closely related to those reported by first time for compounds of general formula 1⁄2CuðBÞðAdeHÞðH2OÞ H2O, with B1⁄4N-benzylor N-(p-methy...
Computational chemistry has recently introduced the improved reaction field theory and now is capable of evaluating the bulk solvent effect quite accurately. It is time to expand this capability to mixed solvents, as it is often extremely useful through is still not well understood. For example, the determination of rates of complexations of divalent metal ions with a tridentate metal-ion indic...
In [his research endo-3-diphenylphosphino -(IR)(+) camphor as a ligand was synthesised. 1.3 mmol of IrC12(NCPh)2 was added to the solution of 2.7 mmolligand in 15 ml dicloromethane, and after one hour it was evaporated at reduced pressure. By addition of methanol microcrystals of yellow complex of lridium(I) with 78% yield was obtained. Crystal structure of the above complex are orthorho...
Nano dithiocarbamate (DTC) complex have been prepared by reaction between dithiocarbamate and metal salt under ultrasound irradiation. Reaction conditions such as the ligand DTC and phennantroline concentration, aging time and the ultrasonic device power show important roles in the size, morphology and growth process of the final products. The dithiocarbamate complex nanoparticles have been pre...
