Crystal structure of strontium thio-sulfate monohydrate
1Technische Universität München, Department of Chemistry, Lichtenbergstr. 4, 85747 Garching, Germany.
Abstract:
SrS2O3·H2O was obtained from an aqueous solution of Na2S2O3 and Sr(NO3)2 and crystallizes in space group P with all atoms at general positions. The Sr2+ ion exhibits an [8 + 1] coordination defined by two terminal S and six O atoms of thio-sulfate ions, one of the latter at a longer distance, and by one O atom of a water mol-ecule. Two thio-sulfate anions act as bidentate, four as monodentate ligands. The structure consists of mainly ionically inter-acting layers lying parallel to the crystallographic ab plane. The layers are connected by O-H⋯S and O-H⋯O hydrogen bonds of moderate strength.

Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...

02:46Crystal Field Theory - Tetrahedral and Square Planar Complexes
Crystal field theory (CFT) is applicable to molecules in geometries other than octahedral. In octahedral complexes, the lobes of the dx2−y2 and dz2 orbitals point directly at the ligands. For tetrahedral complexes, the d orbitals remain in place, but with only four ligands located between the axes. None of the orbitals points directly at the tetrahedral ligands. However, the dx2−y2 and dz2 orbitals (along the Cartesian axes) overlap with the ligands less than the dxy,...
