title: Di-mu-sulfido-bis[diaqua(18-crown-6)barium(II)]-saccharin (1/2).
abstract: The molecule of the title compound [systematic name: di-mu-sulfido-bis[diaqua(1,4,7,10,13,16-hexaoxacyclooctadecane-kappa(6)O)barium(II)] bis[1,2-benzisothiazol-3(2H)-one 1,1-dioxide]], [Ba(2)S(2)(C(12)H(24)O(6))(2)(H(2)O)(4)](C(7)H(5)NO(3)S)(2), lies on an inversion centre. The Ba(II) atom encapsulated by the 18-crown-6 ring is coordinated by the six O atoms of the crown, two water O atoms and two bridging S atoms. The four-membered ring composed of the Ba(II) atoms and the bridging S atoms makes a dihedral angle of 67.1 (1) degrees with the crown-ether ring. The aromatic ring system of the saccharin moiety is essentially planar. The packing is built up from layers of the molecules and is stabilized by three intermolecular O-H.O hydrogen bonds.
