The Y2Se3-Cu2Se-GeSe2 system was investigated using X-ray powder diffraction. The existence of the Y(2+x)/3Cu2-xSe2 (0 _ x _ 1) solid solution (Er2/3Cu2S2 structure type, space group P3) was confirmed in the Y2Se3-Cu2Se section. No compounds were found in the Y2Se3-GeSe2 section. The formation of the Cu8GeSe6 (Cu8GeSe6 structure type, space group P63cm) and Cu2GeSe3 (Cu2GeSe3 structure type, space group Imm2) compounds was confirmed in the Cu2Se-GeSe2 section. The isothermal section of the Y2Se3-Cu2Se-GeSe2 system at 870 K was constructed, based on data of the phase analysis of 54 samples. The formation of new quaternary Y3CuGeSe7 compound (La3CuSiS7 structure type, space group P63, a = 1.02368(8) nm, c = 0.60569(3) nm) was established in the Y2Se3-Cu2Se-GeSe2 system.
