“…Furthermore, these phases exhibit small homogeneity ranges. Precise refinements of the occupancy parameters revealed the compositions Sc 50 Co 12.5 In 3.5 (VEC 273) [11] During our recent phase, analytical studies in the scandium-rich parts of the Sc-T-In systems, besides Sc 2 CoIn [11], Sc 14 Co 3 In 3 [15], Sc 5 CuIn 3 [16], and Sc 5 Cu 2 In 4 [17], we obtained the new members of the Sc 50 T 13 In 3 series with T = Ni, Ru, and Pd, decreasing VEC to 263 for Sc 50 Ru 13 In 3 . The synthesis and crystal chemistry of these new scandiumrich intermetallics are reported herein.…”

The scandium-rich intermetallic compounds Sc50T13In3 (T = Ni, Ru, Pd) were synthesized from the elements in sealed tantalum crucibles in an induction furnace. The samples were studied through Guinier powder patterns and their structures were refined from single-crystal X-ray diffractometer data. The Sc50T13In3 phases are site occupancy (coloring) variants of the aristotype Ag7+xMg26–x (Fm$$ \bar{3} $$ 3 ¯ , cF264). Refinements of the occupancy parameters indicated one mixed occupied site for each crystal, leading to the refined compositions Sc50Ni13.16(1)In2.84(1), Sc49.59(1)Ru13In3.41(1), and Sc50Pd13.65(2)In2.35(2). The complex structures can be explained by a condensation of cubes (CN 8), sphenocorona (CN 10), and icosahedra (CN 12). The samples with nickel and palladium are Pauli paramagnets. Graphic abstract

Polycrystalline Sc5Cu2In4 was synthesized by induction melting of the elements and small single crystals were obtained by a slow cooling sequence. Sc5Cu2In4 is the first coinage metal representative in the family of the so-called 5-2-4 intermetallics. The Zr5Ir2In4 type structure of Sc5Cu2In4 was refined from single crystal X-ray diffractometer data: Pnma, a = 1716.75(6), b = 677.94(12), c = 760.69(2) pm, wR2 = 0.0531, 1932 F2 values and 58 variables. Sc5Cu2In4 adopts a superstructure of the Lu5Ni2In4 type (doubling of the b axis and klassengleiche symmetry reduction from Pbam to Pnma), caused by dislocation of the copper atoms (puckering effect). Geometrically, Sc5Cu2In4 is a 4:1 intergrowth structure of distorted AlB2 and CsCl related slabs.
