S.T.Bayramova, V.M.Ragimova, S.M.Agapashayeva, O.M.Aliyev

 The sulfides of MCuSbS3 and MCuBiS3 (M=Pb, Eu, Yb) kind have been synthesized for the first time and their some physico-chemical properties have been studied. It has been determined that obtained compounds crystallize in rhomb: PbCuSbS3а=8.160, b=8.72, с=7.8 Å; EuCuSbS3 а=8.156, b=8.68, с=7.786 Å; YbCuSbS3 а=8.15, b=8.64, с=7.76 Å; EuCuBiS3 а=11.28, b=11.62, с=4.00 Å; YbCuBiS3 а=11.26, b=11.58, с=3.96 Å. The thermodynamics functions of obtained compounds have been calculated by calculation method
