Abstract :
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 Ca2GaCu2 structure type in space
group Immm. Its main features are characterized by linear (Pt—PtPt—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].
