Abstract

The new compound TlCuTiTe3 has been synthesized from Tl5Te3 and the corresponding elements and characterized by single-crystal X-ray diffraction methods. TlCuTiTe3 crystallizes in the space group C22h-P21/m of the monoclinic system with two formula units in a cell of dimensions a = 8.409(8) Å, b = 3.956(3) Å, c = 10.261(8) Å, β = 111.56(4)°, V = 317.5(4) Å3 (T= 115 K). The two-dimensional structure comprises slabs of alternating pairs of Ti octahedra and Cu tetrahedra. The slabs are separated by Tl+ cations coordinated to Te2- anions in a monocapped trigonal prismatic fashion. Whereas the structure of the individual slabs in TlCuTiTe3 is strikingly similar to those found in the related materials NaCuTiS3, NaCuZrSe3, and NaCuZrTe3, the packing of the slabs is different. Two-probe resistivity measurements indicate that TlCuTiTe3 is a semiconductor.
