The scandium-rich indide Sc 50 Pt 13.47 In 2.53 was obtained by induction melting of the elements and subsequent annealing. The structure of Sc 50 Pt 13.47 In 2.53 has been refined from single-crystal X-ray diffractometer data: Fm 3 ¯ $\overline{3}$ , a = 1774.61(3) pm, wR2 = 0.0443, 1047 F 2 values and 35 variables. Sc 50 Pt 13.47 In 2.53 is isopointal with the intermetallic phases Sc 50 Co 12.5 In 3.5 , Sc 50 Rh 13.3 In 2.7 , Sc 50 Ir 13.6 In 2.4 , Ag 7+x Mg 26−x and Ga 4.55 Mg 21.85 Pd 6.6 (Pearson code cF264 and Wyckoff sequence ih 2 fecba). Two of the eight crystallographic sites in the structure show mixed occupancies: M1 (≡Pt2 0.70 In1 0.30 ) and M2 (≡Pt3 0.76 In2 0.24 ). The structure contains four basic polyhedra: M2@Sc 8 cubes, Pt1@Sc 10 sphenocorona and slightly distorted M1@Sc 12 and In3@Sc 12 icosahedra. The polyhedra are condensed via common scandium corners and edges. The various Sc–Sc distances range from 302–334 pm and are indicative of substantial Sc–Sc bonding, stabilizing the Sc 50 Pt 13.47 In 2.53 structure. [ABSTRACT FROM AUTHOR]
