Abstract

The crystal structures of monoaquabis(2,2'-bipyridyl)copper(II) disulphonatotrisulphane, C2o HIsCuN4 O2÷. O6S 2-, [Cu(C10HsN2)2(H20)]SsO6, (I) and bis[bis(2,2'-bipyridyl)monochlorocopper(II)] disulphonatotrisulphane hexahydrate, 2C20H16C1CuN+.O6S2-.6H20, [Cu(C10HsN2)2C1]2SsO6.6H2 O, (II) have been determined by X-ray analysis. (I) crystallizes in the monoclinic space group P2~/c with a = 7.651 (2), b = 12.980 (3), e = 26.140 (5) A, fl = 95.50 (5) °, Z = 4; (II) crystallizes in the triclinic space group C1 with a -20.577(4) , b = 14.177 (3), c = 8 .726(2) A, a = 94.72 (5), f l = 101.91 (5), y = 92.03 (5) °, Z = 2. Both structures involve a distorted five-coordinate [Cu(bpy)2X] 2+ cation and disulphonatotrisulphane anions. (I) involves the first structure reported in the solid state of a monoaquabis(2,2'-bipyridyl)copper(II) cation, while (II) involves the most distorted bis(2,2'bipyridyl)monochlorocopper(II) cation. Both complexes involve the disulphonatotrisulphane anion with the previously unreported trans $5 chain configuration.
