  Synthesis and solution properties of some trans-cyanoacidotetraamminechromium(III) complexes

  摘要：

  The trans-[Cr(NH3)4(CN)X]+ ions, where X = NCS, F and Cl, have been prepared by reaction in methanol suspension of either trans-[Cr(NH3)4(H2O)(CN)]2+ with NCS- and F-, or trans-[Cr(NH3)4(Me2SO)Cl]2+ with CN-. Their perchlorate salts have been characterized by analysis, ion-exchange, conductance, absorption spectra, phosphorescence in room-temperature solution and aqueous chemistry. The solvent dependence of the ligand-field spectrum for X = F is ascribed to hydrogen bonding that affects the Cr-F interaction. Both pi(X) --> e(g)*(Cr) and t2g(Cr) --> pi*(CN) charge-transfer transitions are observed, consistent with the pi-donor and pi-acceptor nature of the two axial ligands. All these complexes undergo acid-catalysed CN- aquation. When X = Cl this competes with pH-independent loss of X. The aquation products, fully stereoretentive, confirm the trans isomerism of the new species. The anation and aquation behaviours reveal trans effects of the CN- ligand.
