Crystal structure of Sr(2)CdPt(2) containing linear platinum chains

The ternary inter­metallic title phase, distrontium cadmium diplatinum, was prepared from stoichiometric amounts of the elements at 1123 K for one day. The crystal structure adopts the ortho­rhom­bic Ca(2)GaCu(2) structure type in space group Immm. Its main features are characterized by linear (Pt—P...

Sumario:The ternary inter­metallic title phase, distrontium cadmium diplatinum, was prepared from stoichiometric amounts of the elements at 1123 K for one day. The crystal structure adopts the ortho­rhom­bic Ca(2)GaCu(2) structure type in space group Immm. Its main features are characterized by linear (Pt—Pt⋯Pt—Pt)(n) chains that are aligned along [010] and condensed through cadmium atoms forming Cd-centred Pt(2)Cd(2/2) rectangles to build up sheets parallel to (001). These sheets are connected to each other via alternating (001) sheets of strontium atoms along [001]. The strontium sheets consists of corrugated Sr(4) units that are condensed to each other through edge-sharing parallel to [100].
