Racemic calcium tartrate tetrahydrate [form (II)] in rat urinary stones

Résumé

The title compound, [Ca(C 4 H 4 O 6 )]·4H 2 O, calcium tartrate tetrahydrate, is a new triclinic centrosymmetric form identified in rat kidney calculus. The crystal structure was determined from powder and single-crystal X-ray diffraction. The four water molecules belong to one square face of the Ca-atom coordination (a square antiprism), the four O atoms of the second square face coming from two tartrate anions, building infinite chains alternating Ca atom polyhedra and tartrate anions along a , with the chains cross-linked by a network of hydrogen bonds.
