An unusual mixed crystal of a square-pyramidal oxorhenium(V), [ReOCl(Hdua)], and an octahedral imidorhenium(V) complex, [Re(dua)Cl2(PPh3)], was prepared from the reaction of trans-[ReOCl3(PPh3)2] and (6Z)-6-(2-aminobenzylideneamino)-5-amino-1,3-dimethylpyrimidine-2,4(1H,3H)-dione (H3dua) in ethanol. Characterization was performed by single crystal X-ray structure determination and IR spectroscopy. The chelate Hdua is coordinated as a tridentate diamido-imine, and dua is chelated as an imido-imino-amide.
