One step synthesis of [Rh(bpy)2DHAQ] X2 {DHAQ= 1,8-dihydroxy-anthraquinone, bpy= 2,2'-bipyridine, X= Cl- or PF6-} using microwave technique is described. Comparison between conventional and microwave methods is discussed. Microwave method remarkably improves the purity of the product, eliminates the two hours refluxing period and minimizes the solvent amount to almost a negligible quantity. The results support the use of microwave techniques in the synthesis of transition metal complexes.
