New mixed-valent copper chalcogenides BaCuS_{3-x} and K_{3}Cu_{8}X_{6} with X=Se or Te and KCu_{3}Se_{2}, with chemical patterns corresponding to the recently investigated K_{3}Cu_{8}S_{6} and KCu_{3}S_{2}, were synthesized. For these new samples the results of resistivity and magnetic susceptibility measurements are presented. For BaCuS_{3-x}, K_{3}Cu_{8}Se_{6} and KCu_{3}Se_{2} the metal-insulator transition is observed with the low temperature phase being metallic, which is untypical, whereas K_{3}Cu_{8}Te_{6} is a metal in the investigated temperature range. The temperature dependence of magnetic susceptibility of the studied samples testifies to their diamagnetic or weakly paramagnetic behaviour.
