Structural, Optical, and Redox Properties of Lamellar Solids Derived from Copper(1) Complexes and n-Butylammonium Uranyl Phosphate and Arsenate
Abstract
A family of hydrated, layered solids has been prepared from intercalative ion exchange reactions of n-butylammonium uranyl phosphate (BAUP) or arsenate (BAUAs), (n-C4H9NH3)-UO2E04.3H2O (E = P, As), with Cu(LL)2+ complexes (LL is dmp = 2,9-dimethyl-4,7-diphenyl-1,10-phenanthroline; or bcp = 2,9-dimethyl1-1,10-phenanthroline). The products obtained were analyzed as having compositions (Cu(LL)2)x(BA)1-xU02E04.2H20 with x approx.0.2. Xray powder diffraction data reveal that the compounds are single phases that can be indexed on the basis of a tetragonal unit cell. The solids exhibit absorption and photoluminescence (PL) properties characteristic of the Cu(LL)2+species; the Cu(I) complexes completely quench the uranyl PL. Once intercalated, the Cu(I) complexes can be oxidized using Br2 vapor and re-reduced either photochemically or by N2H4 vapor, as shown by changes in electronic and EPR spectra. Keywords: Copper compounds; Phenanthrolines; Uranium compounds; Arsenic compounds.
