Solitary confinement : Ba 2 Pt (see structure) which contains isolated platinide ions (Pt 2− ) was synthesized from the elements, sealed in tantalum ampoules, at 1223 K in argon. In contrast to the related Cs 2 Pt, the Ba compound contains excess electrons, which are responsible for its metallic behavior. The presence of isolated Pt 2− ions was confirmed by high resolution X‐ray diffraction and by theoretical calculations.
