A new ternary compound Al14 Dy5Si was discovered and studied by means of X-ray powder diffraction technique. The ternary compound Al14Dy5Si has a hexagonal BaPb3-type structure, space group R 3m(No. 166), the lattice parameters a =0.61482(1) nm, c =2.09780(2) nm. The crystal structure of the compound Al14Dy5Si was successfully refined by using Rietveld method from X-ray diffraction data. The R-factors of Rietveld refinement are RP= 0.091 and Rwp = 0.120, respectively. The thermal dependence of the magnetization (M-T curves) for the compound was measured by a vibrating sample magnetometer. The experimentally determined magnetic effective paramagnetic moment isμeff = 23.22μB per formula unit (10.36μB per Dy atom).
