摘要：

A new phase in the ternary Tl-Ag-Te system has been identified. X-ray diffraction examination of single crystals was used to establish the crystal structure of Tl2Ag16Te11. The hexagonal space group is R3cBAR and the lattice parameters are a = 1.1442(3) nm, c = 4.1971(5) nm and Z = 6. The structure is described as a three-dimensional array of large hexagonal channels of silver and tellurium atoms hosting linear chains of atoms. These channels are parallel to the crystallographic c axis. Each channel is built up with hexagonal prisms centred by thallium atoms and with tellurium-centred silver octahedra. The refinement indicates partial occupation of all silver positions.
