| Abstract: | The crystal structure of the compound Sm4Pd4Si3 was determined by the single-crystal method (KM-4 automatic diffractometer, Mo K radiation. Sm4Pd4Si4 has the monoclinic Nd4Rh4Ge, type structure: space C2/c, mC44 (No. 15). a = 20.693(6), B = 5.584(1), C = 7.699(2) Å, β = 109.48(3)°, V = 838 Å, Z = 4, μ - 36.23 mm1, R =F = 0.0537, R F = 0.0435 for 1652 unique reflections. The coordination numbers of samarium atoms are 17 and 18. For palladium and silicon atoms icosahedra and trigonal prisms with additional atoms are typical as coordination polyhedra. The structure of Sm4Pd4Si4 is composed of fragments of the YPd2Si and Y1Rh2Si2 structure in a ratio 1:1. |
