The crystal structure of the novel compound SmPd₂In₄ was determined from single-crystal X-ray diffraction data. The indide crystallizes in a new structure type; Pearson symbol oP112, space group Pnma, a = 52.597(9) Å, b = 4.5074(8) Å, c = 9.8875(19) Å, Z = 16. It orders antiferromagnetically near 10 K possibly with a complex magnetic structure that involves as many as four crystallographically independent sites of Sm atoms.
