Abstract

The acid-base reaction of 1,4-benzodioxane 2-carb-oxy-lic acid with calcium carbonate furnished the centrosymmetric title compound, [Ca(C9H7O4)2(H2O)4], in which the metal ion is octa-hedrally coordinated by two monodentate 1,4-benzodioxane 2-carboxyl-ate ligands and four water mol-ecules. In the crystal, O-H⋯O and C-H⋯O hydrogen bonds link the mol-ecules into a three-dimensional network.

Keywords: 1,4-benzodioxane; calcium atom; carboxyl­ate groups; crystal structure; hydrogen bonding.
