Abstract: | The Voronoi-Dirichlet polyhedra (VDP) and the method of intersecting spheres were used to carry out crystal chemical analysis of 85 compounds containing 124 PtCn or PtCnPtm coordination polyhedra in which the Pt-C and Pt-Pt bond lengths vary in the 1.82-2.43 and 2.58-2.98 Å ranges. The main stereochemical features of platinum are discussed depending on the nature (C or Pt) and the number (n varying from 1 to 10; m varying from 0 to 9) of atoms in the first coordination sphere. It is shown that the VDP parameters can be used to identify the aghostic Pt···H-C interactions in the crystal structure. |
