rr~ns-[Rh(en)~(H~O>Cl]~+ was prepared in situ by aqueous solution and the other prepared by a solidirradiating an aqueous solution of tr~ns-[Rh(en)~Cl~]- state reaction. C104. ~runs-[Rh(en)~BrCl]ClO~ was isolated in 80% All complexes were determined to be trans isomers yield by treatment of this solution with silver ion and by their characteristic infrared spectrae6 bromide ion in the manner above. The ultraviolet Extensive application has been made of the photospectra of both of these compounds agree with those chemical syntheses of organometallic c o m p o ~ n d s . ~ p~blished.~~~~ More use should be made of this approach for the syntheses of Werner complexes, particularly complexes of the platinum metals which are often otherwise difficult to prepare.
