摘要：
The electrochemical corrosion of zinc in a zinc/ iron-pair leads in a barium containing solution of hydroxozincate at room temperature to colourless platelets of BaZn(OH)(4) . H2O. The X-ray structure determination on these crystals was successful. Hydrogen positions could not be determined. Pna2(1), Z = 12, a = 11.786(1)Angstrom, b = 17.972(2)Angstrom, c = 7.9336(6)Angstrom, N(F-0(2) greater than or equal to 2 sigma F-0(2)) = 1692, N(Var.) = 71, R-1/wR(2) = 0.055/0.099. In BaZn(OH)(4) . H2O the coordination polyhedra of 8 O around Ba build face-sharing chains. Three of these chains are connected via edges. Isolated tetrahedra of O around Zn bridge these chains three-dimensionally.
