The ternary Laves phases Sc0.22(1)Ta0.78(1)Fe2 and Sc0.63(1)In0.37(1)Co2 were synthesized by arc-melting appropriate amounts of the binary ScFe2 TaFe2 or Sc, In Co, respectively. samples studied powder X-ray diffraction structures refined from single crystal data: P63/mmc, a=484.96(7), c=793.17(11) pm, wR2=0.0604, 147 F2 values, 12 variables for P63mc, a=488.61(4), c=1599.54(12) wR2=0.0389, 553...
