In ion-exchange membranes (IEMs), the concentration-induced tradeoff between conductivity and permselectivity constrains process performance. This study investigates impacts of different electrolytes on conductivity-permselectivity commercial cation anion exchange membranes. Nine electrolyte solutions containing mono-, di-, trivalent ions, spanning 1.5 orders magnitude in concentration were exa...

[Sn(OSO3)2(TPyHP)](HSO4)2∙8H2O (1), an ionic Sn(IV)-porphyrin complex, was prepared by reacting [Sn(OH2)2TPyP] with dilute sulfuric acid. X-ray structural analysis revealed that the zwitterionic [Sn(OSO3)2TPyHP]2+ species consists of two anionic axial Sn–O–SO3 units and four peripheral pyridinium moieties, overall dicationic charge balanced hydrogen sulfate (HSO4−) counter-anions. Ionic bonding...

In the structure of the title compound, {[Na(C6H15N3O3)]Br} n , the sodium cation and the bromide anion are both located on threefold rotation axes. The sodium cation is bonded to the three hy-droxy groups of one 1,3,5-triamino-1,3,5-tride-oxy-cis-inositol (taci) ligand, with the taci ligand residing around the same threefold rotation axis as the sodium ion. The coordination sphere of the sodiu...

In the title compound, [Cu(ClO(4))(C(2)H(3)N)(C(15)H(19)N(3)O)]ClO(4), the Cu(II) ion is coordinated by three N atoms and a hydroxyl-O atom of the tetra-dentate ligand, an O atom of a perchlorate ion and an N atom of an acetonitrile ligand giving a tetra-gonally distorted octa-hedral environment around the copper(II) atom. There is an offset inter-complex face-to-face π-π inter-action [centroid...
