The crystal structure of calcium chloride rhenate(VII) dihydrate, CaCl(ReO₄)·2H₂O, investigated at 85 K, consists of calcium cations, chloride anions, rhenate(VII) anions and water mol­ecules. In the nearly tetra­hedral rhenate(VII) anion, all constituent atoms lie on special positions of m2m (Re) and m (O) site symmetries. The Cl⁻ anion and water O atom lie on special positions of m2m and 2 site symmetries, respectively. The Ca²⁺ ion, also on a special position (m2m), is eight-coordinated in a distorted square-anti­prismatic coordination mode. The crystal has a layered structure stabilized by Ca—O coordination bonds and O—H⋯Cl hydrogen bonds.
