Аннотация доклада:
During investigation of ternary Ce-Ir-Si system two new compounds were found and their crystal structures determined. Rietveld refinement of X-ray powder pattern of CeIrSi resulted in a LaIrSi-type structure (P213) and cell parameter a = 0.62945(1) nm. A single crystal experiment for Ce6Ir30Si19 has revealed an isotypism of the new compound with Ce6Rh30Si19 (Sc6Co30Si19-type; P63/m; a = 1.57234(3) nm, c = 0.38924(1) nm). Compositions of both new compounds derived by refinements are in a good agreement with EPMA data.
