| dc.description.abstractEn | Deriving the energy-volume equations of state EOS for Ca<sub>2</sub>PtO<sub>4</sub> in Ca<sub>2</sub>IrO<sub>4</sub>-type and in K<sub>2</sub>NiF<sub>4</sub>-type (knf) structures, leads to energy destabilization at a larger volume for the latter and to propose the former as a post-K<sub>2</sub>NiF<sub>4</sub>–pknf–occurring at high pressures with a reduced dimensionality 2D-knf → 1D-pknf and a rearrangement of the <i>PtO<sub>6</sub></i> octahedra from corner sharing in knf to edge sharing in pknf. Bader charge analysis indicates an increased covalence of Pt–O bond with such a transformation. The lowered dimensionality is also illustrated from the density of states. | |
