 Title    Synthese und Kristallstruktur von Ba(H S04)2(H2S 0 4)3 und Sr(H S04)2(H2S 0 4) Synthesis and Structure o f B a (H S 0 4)2(H 2S 0 4)3 and S r(H S 0 4)2(H 2S 0 4)  
 Abstract    From the binary systems M 2S 0 4/H 2S 0 4 (M = Ba. Sr), two new hydrogen sulfates, (Ba(HS0 4)2(H 2S0 4)3 and S r(H S 04)2(H 2S 0 4), have been synthesized and structurally char­ acterized. Ba(HS0 4)2(H2S0 4)3 crystallizes in the orthorhombic space group P 2 12 12 , with unit cell parameters a = 4.680(1), b = 11.267(2), c = 29.188(6)A, Z = 4. B a 0 9 trigonal prismatic polyhedra with Ba-O distances of 2.68 -3.02 A from nine different S 0 4 tetrahedra are connected via common bases and build "isolated" columns consisting of O-S-O bridged double chains along the .r-axis. H S 0 4 and H2S 0 4 tetrahedra are linked via hydrogen bonds to form columns. S r(H S 04)i(H TS04) crystallizes in the triclinic space group P i with unit cell parameters a = 5.971(1), b = 8.468(2), c = 10.226(2)A, a = 81.71(3), ß = 83.30(3), 7 = 70.69(3)°, Z = 2. Sr is coordinated by nine oxygen atoms from seven different S 0 4 tetrahedra with S r-0 distances of 2.47 -2.84 A. The S r0 9 polyhedra build layers consisting of O-S-O bridged chains. Three crystallographically different S 0 4 tetrahedra are linked via hydrogen bonds to form a kind of flattened cylinder along the .v-axis.
