Acylhydrazones of 2,3-dihydroxybenzaldehyde are easily accessible and afford heterodinuclear helicates; the self-assembly is specific when the resulting coordination compounds are neutral in charge.

We describe the synthesis and characterization of cobalt(II) and nickel(II) coordination compounds of 4[N-(furan-2'-aldimine)amino]antipyrine thiosemicarbazone (FFAAPTS) and 4[N-(4'-nitrobenzalidene) amino]antipyrine thiosemicarbazone (4'-NO(2)BAAPTS). All the isolated compounds have the general composition MX(2)(L)(H(2)O) (M = Co(2+) or Ni(2+); X = Cl, Br, NO(3), NCS or CH(3)COO; L = FFAAPTS o...

The very promising results of Na-trans-[RuCl4(1H-indazole)2] (NKP-1339) in clinical studies have fuelled renewed interest in the research and development of ruthenium(III) coordination compounds for cancer therapy. By applying an improved synthetic approach to this class of coordination compounds, six new examples of the general formula (cation)-trans-[RuCl4(azole)2], where (cation) = tetrabuty...

The synthetic route to ladder-type conjugated imidazolium compounds consisting of Suzuki coupling, chlorination, and intramolecular cyclization reactions was developed. The optical properties of materials and theoretical calculations were investigated to demonstrate that methylene- and ethylene-bridged imidazolium compounds show green and blue fluorescence, respectively. The coordination abilit...

The coordination compounds of Fe (II) and Fe(III) with phthalic acid were synthesized. The compounds were studied by X-Ray Diffraction (XRD), Differential Thermal Analysis (DTA), and IR spectroscopy. It has been established that, regardless of the oxidative number of iron, the synthesis products have the same chemical composition and chemical formula - [Fe2(o-C6H4...

The coordination chemistry of germanium covers quite bulk fields, as shown by a survey covering the crystallographic and structural data of over two hundred examples. About ten percent of those complexes exist as distortion isomers and are summarised. These are discussed in terms of the coordination around the germanium(I), germanium(II) and germanium(IV) atoms, and correlations are drawn betwe...

Various types, shapes and sizes of iron oxide nanoparticles were obtained depending on the nature of the precursor, preparation method and reaction conditions. The mixed valence trinuclear iron acetate, [Fe2IIIFeIIO(CH3COO)6(H2O)3]·2H2O (FeAc1), μ3-oxo trinuclear iron(III) acetate, [Fe3O(CH3COO)6(H2O)3]NO3∙4H2O (FeAc2), iron furoate, [Fe3O(C4H3OCOO)6(CH3OH)3]NO3∙2CH3OH (FeF), iron chromium furo...

Seven morpholin derivatives were synthesized (compounds 1-7) and their behavioural effects were evaluated; the elements considered were locomotor activity, motor coordination, catalepsy, stereotyped behaviour and antinociception. All the compounds, at doses of 10-20-40 mg/kg/i.p., induced a reduction of all behavioural elements without a significant antinociceptive effect. These results indicat...
