Figure 2. The Structure of Pr2Ba4Cu7O15−δ (Pr247) — Caption

Pr247 consists of the alternative stacking of Pr123 and Pr124 unit. Pr247 has four inequivalent Cu sites: single chain Cu(1) site, plane Cu(2) site in the Pr123 unit, plane Cu(3) site in the Pr124 unit, and double chain Cu(4) site. The Cu atoms in the double chain do not form a “ladder” structure but a “double” chain or a “zigzag” chain.
