Abstract: | The crystallochemical analysis of a representative set of the complex [P2S6]4– anions, which has been carried out within the framework of the modern bond valence model, has revealed the high applicability of the bond valence parameters r0 = 2.125 Å and b = 0.37 Å (originally proposed for the P5+/S2– ion pair) to the P4+/S2– ion pair forming the above complex anions. The use of these parameters can help find the poorly determined structural models of thiophosphates and/or instable thiophosphate structures tending to polymorphic phase transitions. The applicability of the same (r0; b) parameters to the P4+/S2– and P5+/S2– ion pairs could be explained by the same number of the Lewis electron pairs involved in the chemical bonding of these ions. |
