摘要：

By means of electron microscopy and diffraction together with EDX and EELS, we have confirmed the main characteristics of the structure of the recently discovered HTSC family of ''copper/carbonate cuprates''. These can be obtained at high pressure and have critical temperatures of the order of 117 K. It consists of a copper/carbonate ordered variant of the tetragonal ''single X-O layered'' cuprate structure. The unit cell is given by a=2a(t), b=b(t) and c=2c(t), where subindex t corresponds to the tetragonal single layer cell.
