Abstract

The structure of Poly[(acetone-O)-3-((3,4-dimethoxyphenyl)(4-hydroxy-2-oxo-2H-chromen-3-yl)methyl)-(2-oxo-2H-chromen-4-olate)sodium] was determined by X-ray crystallography. The compound crystallizes in an orthorhombic system and was characterized thus P , (2) Å, (3) Å, Å. , (10) Å3. The crystal structure was solved by direct methods and refined by full-matrix least-squares on to final values of and .
