SYNTHESIS AND CRYSTAL STRUCTURE OF THE MnGaInSe4 COMPOUND

The compound MnGaInSe4 was synthesized from the ternary compounds MnGa2Se4 and MnIn2Se4 by melting in conditions of vacuum. Its crystalline structure has been made precise on the basis of powder diffraction data by the Rietveld method. It is shown that the compound crystallizes in the trigonal syngony with lattice parameters: a = 3.9812 (1) Å, c = 12.9904 (4) Å, V = 178.32 (1) Å3, space group P-3m1. It was also found that the compounds MnGaInSe4 and ZnIn2S4 are isostructural
