Abstract

Rhodium(III) can be exchanged between the layers of a-zirconium phosphate by employing the pre-swelled diethanol intercalate, alpha-Zr(HPO4)(2)(ethanol)(2). During the Rh3+/H+ exchange, four rhodium-containingphases are formed with different interlayer distances. However, only the fully Rh-III-exchanged compound, alpha-ZrRh0.66(PO4)(2) . 4H(2)O, is obtained as a pure phase. Rhodium(III) can also be exchanged into the layered intercalation compounds alpha-Zr(HPO4)(2)(bipy)(0.25) . 1.5H(2)O (bipy=2,2'-bipyridyl), alpha-Zr(HPO4)(2)(phen)(0.5). 2H(2)O (phen=1,10-phenanthroline) and alpha-Zr(HPO4)(2)(dmp)(0.5) . 2.5H(2)O (dmp=2,9-dimethyl-1,10-phenanthroline). Exchange is accompanied by a partial elution of the diamine for the phen and dmp derivatives. Various materials are obtained and their thermal properties discussed. X-Ray photoelectron spectroscopy (XPS) gives evidence that Rh-III-diamine complex species (mixed N- and O-coordinated Rh-III are formed in the interlayer region of the three intercalation compounds.
