The syntheses of four new copper oxyselenides with the general formula (MO)(CuSe)(M = Bi, Nd, Gd, Dy) and one copper oxysulfide, BiOCuS, are reported. The tetragonal unit cell dimensions of all compounds are given. A new bismuth-copper oxyselenide, BiOCuSe, has been structurally characterized from powder X-ray diffraction data and finally solved by the Rietveld profile method with R{sub 1} = 0.069. The BiCuSeO crystal structure is formed by alternating [Bi{sub 2}O{sub 2}] and [Cu{sub 2}Se{sub 2}] layers.
