The single crystals with two-leg spin-ladder–type structure were investigated. According to the structural, magnetic, optical and resistivity data obtained, the studied crystals were shown, for the first time, to be high- superconductors (=80 K) which belong to the class of cuprates with incommensurate-type structure.
