title: Triaqua-chlorido(18-crown-6)barium chloride.
abstract: In the title compound, [BaCl(C(12)H(24)O(6))(H(2)O)(3)]Cl, the Ba(II) atom, the coordinating and free Cl(-) anions, one coordinating water mol-ecule and two O atoms of an 18-crown-6 mol-ecule lie on a mirror plane. The environment of the ten-coordinate Ba(2+) ion is defined by one Cl atom, three water mol-ecules and six O atoms from the macrocyclic ether. The macrocycle adopts a conformation with an approximate D(3d) symmetry. In the crystal, O-H⋯Cl hydrogen bonds link the complex cations and Cl(-) anions into a two-dimensional network parallel to (010). An intra-molecular O-H⋯Cl hydrogen bond is also present.
