Hexaaqua­chromium(III) pyridine-2,4,6-tricarboxyl­ate dihydrate

Abstract

The chromium(III) atom in the title salt, [Cr(H ₂O) ₆](C ₈H ₂NO ₆)·2H ₂O, has an octa­hedral coordination geometry. In the crystal, the cation, anion and uncoordinated water mol­ecules, both of which are disordered over two positions in a 1:1 ratio, are linked by O—H⋯O hydrogen bonds.
