The title compound was prepared by condensation of glyoxal and 1,4- diformyl-2,3,5,6-tetrahydroxypiperazine in the presence of nitric and sulfuric acids. Cooling the reaction mixture with ice yielded colorless crystal suitable for data collection. The density was measured at room temperature by flotation in a mixture of tribromomethane and bromochloromethane. Arectangular plate with approximate dimensions 0.6x 0.2x0.6 mm was mounted on an Enraf-Nonius CAD4 diffractometer with graphite crystal monochromator and cooled to 1005K with a stream of cold N2 gas. Lattice parameters were determined from at least-squares refinement of 25 reflections.
