Summary:6Li and 7Li MAS NMR spectra of complex Li2ZN2(MoO4)3 and LiRb3Hf2(MoO4)6 molybdates of lyonsite-type structure are studied at temperatures ranging from 25 to 100°C. NMR signals are attributed to their sources. It is shown that the presence of a transition metal such as Hf in the +4 oxidation state in the structure of lyonsite contributes to the increased mobility of lithium ions along the channels of the crystal structure.
