摘要：

The quaternary indides RE7Ni5-xGe3+xIn6 (RE = La, Nd, Sm) were synthesized from the elements by arc-melting. Single crystals were grown by slow cooling of the polycrystalline samples. The structures were characterized by powder and single-crystal X-ray diffraction: Ce7Ni4.73Ge3.27In6 type, P6/m, Z = 1, a = 1147.05(9), c = 426.82(4) pm, wR2 = 0.0652, 528 F-2 values for La7Ni4.46Ge3.54In6, a = 1134.5(7), c = 407.1(7) pm, wR2 = 0.0419, 441 F-2 values for Nd7Ni4.91Ge3.09In6, and a = 1133.5(2), c = 404.3(1) pm, wR2 = 0.0619, 498 F-2 values for Sm7Ni4.31Ge3.69In6, with 25 parameters per refinement. Characteristic features of the RE7Ni5-xGe3+xIn6 structures are hexagonal, AlB2-related prisms around the RE1 atoms and a tricapped, trigonal-prismatic coordination of the nickel atoms.
