New ternary CeScSi-type RZrSb compounds (R=Y, Gd-Tm, Lu)

Investigations made by powder X-ray diffraction on eight new ternary RZrSb compounds (R=Y, Gd-Tm, Lu) are reported. The YZrSb (a=0.4245(1) nm, c=1.630 6(3) mu), GdZrSb (a=0.4261(1) nm, c=1.6455(2) nm), TbZrSb (a=0.4251(1) nm, c=1.6380(2) nm), DyZrSb (a=0.4240(1) nm c=1.6349(2) nm), HoZrSb (a=0.4201(1 ) nm, c=1.6143(2) nm), EZrSb (a=0.4204(1) nm, c=1.6159(2) nm), TmZrSb (a=0. 4174(1) nm, c 1.5997(2) nm) and LuZrSb (a=0.4178(1) nm, c=1.5952(3) nm) cry stallize in the tetragonal CeScSi-type structure (space group 14/mmm).
