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.
