Abstract: Lattice dynamical calculations on SnMn$i.,-type (ordered deficient NaCl superstructure) Li2CoCb and Li2MnBr4 were performed using a short-range force constant model. The results obtained reveal that the assignments of the Raman active phonon modes (and those of the structure related Suzuki- type LisMuX8) reported in the literature have to be changed.The 11 hitherto unknown infrared active modes have been calculated to range 233-339 and 70-98 cm f The 11 hitherto unknown infrared active modes , and 227-266 and 50-71 cm-’ for Li2CoC4 and LizMnBr4, respectively.
