The modes of action of the commercial solvent extractants used in extractive hydrometallurgy are classified according to whether the recovery process involves the transport of metal cations, M(n+), metalate anions, MXx(n-), or metal salts, MXx into a water-immiscible solvent. Well-established principles of coordination chemistry provide an explanation for the remarkable strengths and selectivit...

In the title salt, (C(11)H(10)NO(2))[SnCl(4)(C(10)H(6)NO(2))]·CH(3)OH, the Sn atom is chelated by the quinolincarboxyl-ate unit and it exists in a distorted octa-hedral coordination geometry. The cation is linked to the solvent mol-ecule by an N-H⋯O hydrogen bond; the solvent mol-ecule is linked to the anion by an O-H⋯O hydrogen bond.

Reduction of imines by [2,5-Ph2-3,4-Tol2(eta(5)-C4COH)]Ru(CO)2H (2) produces kinetically stable ruthenium amine complexes. Reduction of an imine by 2 in the presence of an external amine trap gives only the complex of the newly generated amine. Reaction of 2 with H2N-p-C6H4N=CHPh (11), which contains an intramolecular amine trap, gave a 1:1 mixture of [2,5-Ph2-3,4-Tol2(eta(4)-C4CO)](CO)2RuNH(CH...

A 3D 2-fold interpenetrated porous coordination polymer, [Fe(NCS)2(tppm)]·5CH3OH·2CH2Cl2 (·sol, tppm = 4,4',4'',4'''-tetrakis(4-pyridylethen-2-yl)tetraphenylmethane), was synthesized, which showed temperature, light and solvent-induced spin-crossover behaviours.

The new porous phosphine coordination material, PCM-11, is an unusual 8,4-connected coordination polymer with an open 3-D pore structure, formed by reaction of Mg(II) with tris(para-carboxylato)triphenylphosphine oxide. The highly ionic nature of the metal-ligand bonding results in excellent thermal stability upon desolvation (>460 °C). PCM-11 is easily activated for small molecule sorption at ...

In the title coordination polymer, {[CdI(2)(C(13)H(11)N(3))]·0.5CH(4)O}(n), each Cd(II) center is four-coordinated by two N-atom donors from two 1-(4-pyridylmeth-yl)-1H-benzimidazole (L) ligands and two iodide anions, forming a tetra-hedral coordination geometry. L ligands bridge adjacent Cd(II) ions, generating two crystallographically independent approximately orthogonal one-dimensional chain...

• Combined ultrasound and solvent assisted synthesis of 2D coordination polymers. Role interstitial molecules in the delamination 2D-CPs. Influence sonication time nanostructuration processes. Morphological supramolecular transformations Herein, a new 2-dimensional polymer based on copper (II), {Cu 2 (L)(DMF) } n , where L stands for 1,2,4,5-benzenetetracarboxylate (complex 1 ) is synthesized. ...

In the title Ru(II) complex, [RuCl(2)(C(8)H(12))(C(2)H(3)N)(2)]·CH(3)CN, the metal ion is coordinated to the centers of each of the double bonds of the cyclo-octa-diene ligand, to two chloride ions (in cis positions) and to two N-atom donors (from MeCN mol-ecules) that complete the coordination sphere for the neutral complex. The coordination about the Ru(II) atom can thus be considered to be o...
