Abstract

The scandium-rich phase Sc14Co3.10In2.59 has been synthesized by a direct reaction of the elements in a sealed tantalum ampoule in a high-frequency furnace. Single crystals were obtained by slow cooling of the product. The Sc14Co3.10In2.59 structure was refined from single-crystal X-ray diffractometer data: Lu14Co3In3 type, P42/nmc, a = 889.13(13), c = 2138.7(4) pm, wR2 = 0.0483, 1636 F2 values, and 64 variables. Sc14Co3.10In2.59 completes the series of the rare earth metal-rich phases RE14Co3In3. The structure refinement revealed defects on the Co1 site (84.7(5)% occupancy on 8g) and a mixed occupancy of 59.1(7)% In1/40.9(7)% Co3 on the 4c site. The structure is built up by a dense condensation of Co@Sc6 trigonal prisms and In2@InSc11 and In1/Co2@Co2Sc10 icosahedra. An interpenetration of the In2@InSc11 icosahedra leads to dumb-bell formation with an In2–In2 distance of 289 pm. The Sc14Co3.10In2.59 structure is stabilized by substantial Sc–Sc bonding (316–360 pm Sc–Sc).
