BaCu 2 Te 2 was synthesized at 6903C and its structure was determined via the Rietveld re5nement method using powder X-ray di4raction with R p /wR p (%) ؍ 4.01/5.36. BaCu 2 Te 2 crystallizes in the orthorhombic space group Pnma (No. 62) with Z ؍ 4 and a ؍ 10.1244(5) A > , b ؍ 4.4577(3) A > ,
The crystal structure of \(\mathrm{BaCu}_{2}\left(\mathrm{PO}_{4}\right)_{2}\) has been determined from X-Ray single crystal data. The crystal symmetry is triclinic, space group \(P \overline{1}\), with unit celt constants \(a=9.226(1) \AA, b=9.271(1) \AA, c=\) 10.516(1) \(\AA, \alpha=106.76(5)^{\ci
