| [Ni(NH3 )6]S0 4 : Kristallstruktur und Infrarotspektren [Ni(NH3)6]S 0 4: Crystal Structure and Infrared Spectra  | | | | Abstract
| The crystal structure of [Ni(NH3)6]S 0 4 has been determined by single-crystal X-ray dif fraction (P2,/c; Z = 4; a = 705.0(1), b = 1195.2(2), c = 1180.0(2) pm, ß = 96.14(3)°; 2271 reflections; R x = 3.94%). In the hitherto unknown structure type, both the [Ni(NH3)6]2+ and the S 0 42-ions form chains along [100], The six crystallographically different ammine ligands of the distorted [Ni(NH3)6]2+ octahedra are involved in hydrogen bonds to six crystallographically equivalent S 0 42-ions (site symmetry C |). The strength of the hydrogen bonds differs strongly (i'od ° f matrix isolated N H 2D molecules: 2378 -2494 cm -1 , N -O distances: 272 -340 pm). The temperature evolution of the IR bands reveals the decrease of the dynamic orientational disorder of the N H 3 molecules with decreasing temperature. | | | |
