A mixture of bismuth oxynitrate (22.96 g) and citric acid (33.60 g) in water (80 ml) was heated on a steam bath with frequent stirring for 30 min, by which time one drop of the suspension added to weak aqueous ammonia gave a clear solution. The mixture was diluted with water, filtered, and the residue washed well with water until free of nitrate and excess citric acid. The residue was dried under vacuum to give the title compound (32.18 g).
