In the title compound, [Cu(C7H3NO4)(C3H4N2)(H2O)]·2H2O, the CuII atom is coordinated by three O atoms and two N atoms, provided by a tridentate pyridine-2,6-di-carboxyl-ate (pdc), one pyrazole and one water ligand, forming a slightly distorted square-pyramidal geometry [range of O-Cu-O and O-Cu-N bond angles = 79.55 (8)-166.22 (10)°]. The water mol-ecule is positioned at the apical position. In...

Prussian blue analogues are being explored as electrode materials for electrochemical desalination of saline water in battery-type deionization systems and hybrid capacitive due to their open framework crystal structure that provides selective adsorption multiple cations, high theoretical sodium capacities, low costs. However, poor electronic conductivity instability (dissolution) prevents the ...

The title dinuclear copper(II) complex [Cu2(C18H16Br2N2O4S2)2] was prepared by direct synthesis of a dianionic Schiff base derived from 5-bromo-salicyl-aldehyde and cyste-amine. The discrete mol-ecules lie across inversion centers and crystallize with two di-methyl-formamide (DMF) mol-ecules of crystallization. The unique CuII ion is four-coordinated by two tetra-dentate Schiff base ligands in ...

Six novel one-dimensional chloro-bridged ReIVCuII complexes of formula {[Cu(L)4][ReCl6]}n, where L = imidazole (Imi, 1), 1-methylimidazole (Meim, 2), 1-vinylimidazole (Vim, 3), 1-butylimidazole (Buim, 4), 1-vinyl-1,2,4-triazole (Vtri, 5) and N,N'-dimethylformamide (DMF, 6) are characterised structurally, magnetically and theoretically. The structures exhibit significant differences in Cu-Cl bon...

The ditopic molecule 3-(1,3,5-trimethyl-4-1H-pyrazolyl)acetylacetone (HacacMePz) combines an acetylacetone group suitable for deprotonation and O,O? coordination to a Pearson hard cation with softer N-donor site. Both binding modes were employed individually: the pyrazolyl moiety was coordinated ZnII, HgII, AgI, trivalent iron tris-chelating complex [Fe(acacMePz)3] isolated. CuII derivative sho...
