S. H. Dale and M. R. J. Elsegood

Abstract: The title compound, [Ca(C₈H₄O₄)(H₂O)₃]_n, has been previously studied by single-crystal X-ray diffraction at both room temperature [Matsuzaki & Iitaka (1972). Acta Cryst. B28, 1977-1981] and 173 K [Groeneman & Atwood (1999). Cryst. Eng. 2, 241-249.]. We present here a redetermination of the compound at 150 K, which results in a considerably improved precision and the location of H atoms in the strong O-HO hydrogen bonds.
