The novel compound Sc5CuIn3 was prepared by arc-melting elemental constituents under argon atmosphere and subsequent annealing at 870 K for 40 days. Its crystal structure was determined from the single crystal X-ray diffraction data and its magnetic properties were characterized by means of SQUID measurements performed down to 1.72 K in magnetic fields up to 70 kOe. The compound was established to crystallize with a hexagonal structure of the Hf5CuSn3 type (space group P63/mcm, No. 193, lattice parameters: а = 8.6089(6), с = 6.2029(6) Å, Z = 2, R1 = 0.0354, wR2 = 0.0853), closely related to Mn5Si3 and Ti5Ga4 types. Sc5CuIn3 was found to exhibit a Pauli paramagnetic behavior with the molar magnetic susceptibility of about 5× 10−4 emu/mol. •Formation of the novel compound Sc5CuIn3 has been established.•The crystal structure has been determined from the single-crystal XRD.•The compound adopts the Hf5CuSn3 structure type.•The Sc5CuIn3 compound was established to be a Pauli paramagnet.
