摘要：

The systems MnGa2S4-MnV2S4, MnGa2S4-MnTi2S4 and the corresponding magnesium systems MgGa2S4-MgV2S4 and MgGa2S4-MgTi2S4 were studied by x-ray diffraction methods on quenched powder samples. In all four systems new quaternary compounds crystallizing in a layered structure have been obtained. MgGa1.6Ti0.4S4 (a = 370.9, c = 1219.1 pm) adopts a structure of alpha-FeGa2S4-type while MnGa1.6Ti0.4S4 (a = 370.9, c = 1219.0 pm) and MnGa1.8V0.2S4 (a = 370.2, c = 3652 pm) are of ZnIn2S4(IIIa)-type at 700-degrees-C and undergo a phase transition to the alpha-FeGa2S4 type at 960-degrees-C. Samples of MgGa1.6V0.4S4 consist of a mixture of both layered structures.
