Abstract:
The ternary system SrBr(2)-CdBr(2)-H(2)O was investigated at room temperature. The title phase, SrCd(2)Br(6) x 8H(2)O, has been isolated from this system and its structure determined by single-crystal X-ray diffraction. The structure consists of infinite double chains of CdBr(6) octahedra and chains of Sr(H(2)O)(9) polyhedra packed along the b axis. The interaction between these two isolated chains occurs through O-H.O and O-H...Br hydrogen bonds. The structure is compared with that of SrCd(2)Cl(6) x 8H(2)O.
