New indides, Nd3Ge1.18In0.82 and Sm3Ge1.33In0.67, were synthesized from the elements by arc-melting and subsequent annealing at 870 K. Single crystals were grown through special annealing procedures in sealed tantalum tubes in a resistance furnace. Both compounds were investigated on the basis of X-ray powder and single crystal data: La3GeIn type structure, Pearson code tI80, space group I4/mcm; a = 1200.1(1), c = 1562.8(1) pm, wR2 = 0.0781, 716 F2 values, 34 variables for Nd3Ge1.18In0.82 and a = 1184.7(2), c = 1537.0(3) pm, wR2 = 0.0305, 911 F2 values, 34 variables for Sm3Ge1.33In0.67. The crystal chemistry in Nd3Ge1.18In0.82 is discussed from a geometrical point of view and in terms of LMTO band structure calculations.
