Abstract: The crystal structures of the R4In4.72Se13 (R=La and Ce) compounds (space group Pbam, Pearson symbol oP43.44) were determined by means of X-ray single crystal diffraction (a =1.2442(3)nm, b =2.2146(4)nm, c =0.41969(8)nm, R 1 =0.0426 for La4In4.72Se13) and X-ray powder diffraction (a =1.23725(6)nm, b =2.2144(1)nm, c =0.41463(2)nm, R I =0.0984 for Ce4In4.72Se13). The R atoms are surrounded by trigonal prisms with two additional atoms, the In1 atoms by tetrahedra, the In2–In5 atoms by octahedra. The R-centered trigonal prisms form columns along z-axis. The chains of the In1-centered tetrahedra and In2–In5-centered octahedra are also located along z-axis. [Copyright &y& Elsevier]
