Crystal structure of Sr2CdPt2 containing linear platinum chains.
Ontology highlight
ABSTRACT: The ternary inter-metallic title phase, distrontium cadmium diplatinum, was prepared from stoichiometric amounts of the elements at 1123 K for one day. The crystal structure adopts the ortho-rhom-bic Ca2GaCu2 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 Pt2Cd2/2 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 Sr4 units that are condensed to each other through edge-sharing parallel to [100].
