Procedure

0.58 g of fumaric acid was dissolved in a mixture solvent having 40 cm3 of methanol and 12 cm3 of formic acid. Then, under stirring at the normal temperature, into the above solution, a further solution in which 1.0 g of copper acetate was dissolved in 80 cm3 of methanol was dripped. After this solution was left still for a few days, the precipitation product was suction-filtered and dried for 110° C./4 hours, whereby 0.3 g of fumaric acid copper was obtained.
