Investigations made using powder X-ray diffraction on new ternary RTiGe com
pounds (R=La, Ce, Sm) are reported. LaTiGe (a=0.4157(1) nm, c=0.8013(1) nm)
, CeTiGe (a=0.4128(1) nm, c=0.7908(1) nm) and SmTiGe (a=0.4077(3) nm, c=0.7
751(1) nm) crystallize into the well-known tetragonal CeFeSi-type structure
(space group P4/nmm). (C) 1999 Elsevier Science S.A. All rights reserved.
