摘要
The new ternary YbZn0.7Inl.3 compound was synthesized in evacuated quartz ampoules at 900 ℃, followed by annealing at 400 ℃. It crystallized in the UHg2 structure type with a=0.47934（5） nm, c=0.36955（5） nm, V=0.073535（15） nm3. The shortest distances between the atoms in this structure were equal to 0.3696 nm （Yb-Yb）, 0.3328 nm （Yb-M） and 0.2767 nm （M M）, respectively. Magnetization measurements indicated that the title compound exhibited a paramagnetic behavior down to 2 K, with antiferromagnetic-like interactions. Calculated magnetic moment for YbZn0.7inl.3 （μeft =3.86μB/Yb） could indicate mixed valence state of Yb.
