Abstract
Structural investigations on powder samples of Y2Ba4Cu7O15-x with diff erent carbonate content have been performed. Powder x-ray Rietveld ref inements showed the remarkable influence of carbonate incorporation on the lattice parameters. Most important is the decrease of T-c with in creasing carbonate content. We assign these effects to an incorporatio n of the carbonate ion into the crystal lattice, copper vacancies at t he Cu(1) position and a possible misorientation of the copper oxygen s ingle chains. No change of the structure (e.g. superstructure) could b e found.
