 Title    Synthese und Struktur saurer Ubergangsmetallsulfate - Ti(H50 2)(S 0 4)2(H20 ) 2 und Zr(H30 ) 2(S 0 4)3 Synthesis and Structure of Acid Transition Metal Sulfates - Ti(H50 2)(S 0 4)2(H20 )2 and Zr(H30 ) 2(S 0 4)3  
 Abstract    From the ternary system Mn(S 0 4)n/2 / S 0 3 / H20 (Mn+ = Zr4+, Ti3+) two new acid metal sulfates, Ti(H50 2)(S 0 4)2(H20)2 and Zr(H30) 2(S 0 4)3, have been synthesized and structurally characterized. Ti(H50 2)(S 0 4)2(H->0)i crystallizes in the orthorhombic space group Pnma with cell parameters a = 9.858(5), b = 18.32(2), c = 5.437(7)Ä (Z = 4); Zr(H30) 2(S 0 4)3 crystallizes in the triclinic space group PI with cell parameters a = 5.092(2), b = 8.533(3), c = 12.388(6)A, a = 92.95(3)°, ß = 90.89(3)°, 7 = 94.35(3)° (Z= 2). In the titanium compound there are slightly distorted T i0 6 octahedra with T i-0 distances between 1.99 and 2.09 A which are sharing corners with S 0 4 tetrahedra. Through hydrogen bonds layers are formed perpendicular to the 6-axis. These layers are connected by H30 + ions only. The structure of Zr(H30) 2(S 0 4)3 consists of three different S 0 4 tetrahedra and distorted Zr07 polyhedra which are connected via common corners and edges to form columns parallel to the a-axis. The Z r-0 distances vary from 2.13o to 2.18A for equatorial positions, significantly longer than the axial Zr-O distances with 2.05A.
