Abstract: The Sr^II atom in the title compound, {[Sr(C₁₄H₉O₃)(H₂O)₂]·H₂O}n, is chelated by the carboxyl and hydroxyl O atoms of two anions, and is coordinated by two water molecules that function in a bridging mode. The eight-coordinate configuration arises from additional interaction with the carboxyl O atoms which are already involved in chelation in adjacent molecules. The geometry is intermediate between dodecahedral and square antiprismatic in the linear chain structure.
