Abstract
The synthesis of the oxycarbonate Tl0.85Sr4Cu1.85Fe0.30(CO3)O-7 shows for the first time the possibility to stabilize the ''1201''-Sr2Cu(CO3 )O-2 intergrowth by trivalent iron substitution. This compound crystal lizes in the space group P 4/mmm with a = 3.8246(1)Angstrom and c = 16 .5069(4)Angstrom. The combination of the XRD, HREM and Mossbauer techn iques allows the distribution of iron to be determined. The latter sit s on two kinds of sites, copper and thallium. As a consequence, this c opper oxycarbonate, contrary to all other copper oxycarbonates contain ing thallium, does not superconduct.
