摘要：

Investigations made by powder X-ray diffraction on five new ternary R2Ti3Ge4 compounds (R=Gd-Er) are reported. The (Gd-0.97)(2)Ti3Ge4 (a=0.7042(1) nm, b=1.3494(2) nm, c=0.7186(1) nn), (Tb-0.99)(2)Ti3Ge4 (a=0.7019(1) nm, b=1.3457(2) nm, c=0.7156(1) nm), (Dy-0.97)(2)Ti3Ge4 (a=0.6987(1) nm, b=1.3409(2) nm, c=0.7122(1) nm), (Ho-0.96)(2)Ti3Ge4 (a=0.6981(1) nm, b=1.3399(2) nm, c=0.7117(1) nm) and (Er-0.91)(2)Ti3Ge4 (a=0.6962(1) nm, b=1.3367(2) nm, c=0.7099(1) nm) crystallize in the orthorhombic Sm5Ge4-type structure (space group Pnma).
