The phase diagram of the quaternary system LiCl - MnCl[sub 2] - CrCl[sub 3] has been established by high-temperature X-ray diffraction and differential scanning calorimetry (DSC). The mutual solid solubility of the ternary compounds Li[sub 2]MnCl[sub 4] and the novel Li[sub 5]CrCl[sub 8] is relatively small despite the closely related crystal structures. Li[sub 5]CrCl[sub 8] oC28 undergoes a phase transition to a cubic high-temperature polymorph [und cF]56 at 750 K and it melts incongruently at 835 K. The electric conductivity of Li[sub 5]CrCl[sub 8] measured by impedance spectroscopy methods is 2 [times] 10[sup [minus]5][Omega][sup [minus]1]cm[sup [minus]1] at 470 K. That of Li[sub 2]MnCl[sub 4] decreases with the increase in chromium content.
