Abstract |
The new 2-dimensional quaternary chromium thiophosphate, CsCr3P2S10 has been prepared at high temperature via solid state reactions using CsI as a reactive flux. The crystal structure has been determined by single crystal X-ray diffraction techniques. The title compound crystallizes in the rhombohedral space group R-3m. The imposed symmetry of chromium atom is m and it is surrounded by six sulfur atoms in the octahedral geometry. Phosphorus atoms are coordinated by four sulfur atoms in the tetrahedral fashion. These polyhedra are combined to form the two-dimensional infinite anionic layer, 2∞[Cr3P2S10-], and alkali metal cations, Cs+ stay in the van der Waals space between the layers through electrostatic interactions to complete the three-dimensional structures. The classical charge valence can be described as [Cs+][Cr3+]3[P5+]2[S2-]10. |
