摘要：
The new intermetallic compounds Sr2Pd2In and Sr2Pt2In were synthesized from the elements in sealed tantalum tubes in a water-cooled sample chamber of an induction furnace. Both indides crystallize with the HT-Pr2Co2Al-type structure: C2/c, a = 1048.7(2), b = 603.5(2), c = 830.6(1) pm, beta = 103.68(2)degrees, wR2 = 0.0492, 743 F-2 values for Sr2Pd2In; a = 1026.8(2), b = 599.0(1), c = 830.3(2) pm, beta = 103.17(1)degrees, wR2 = 0.0666, 885 F-2 values for Sr2Pt2In with 25 variables per refinement. The shortest interatomic distances occur for the Pd-In (Pt-In) and Pd-Pd (Pt-Pt) contacts. The strontium atoms are embedded in complex three-dimensional polyanionic networks of compositions [Pd2In] and [Pt2In].
