The control of the stoichiometry of Li 1+x Zn 2−y Mo 3 O 8 was achieved by the solid-state-reaction. We found that the best sample that has the chemical composition Li 0.95(4) Zn 1.92(8) Mo 3 O 8 was obtained from the starting nominal composition with Li : Zn : Mo : O=(1+w) : (2.8−w) : 3 : 8.6 with w=−0.1, indicating that the stoichiometry is greatly improved compared to those in the earlier reports. For larger w detailed structural analysis indicates that the mixed sites of Li and Zn are preferentially occupied by Li atoms, as well as the fraction of the non-magnetic secondary phase Zn 2 Mo 3 O 8 decreases. Magnetic susceptibility of the improved stoichiometry powder samples shows a broad hump in the temperature range of 100<T<200K. This suggests that the development of antiferromagnetic correlations at the high temperatures is inherent to the ideal stoichiometric Li Zn 2 Mo 3 O 8 .
