摘要：

The new infinite chain compound Ta4SiTe4has been prepared by reaction of the elements at high temperature. The structure was refined in the orthorhombic space group Pbam with Z = 4 and lattice constants a = 10.536 (3), b = 18.275 (5), and c = 4.799 (1) Å to a final R = 6.1%, Rw= 8.2%. Ta4SiTe4is a new structure type and represents a new class of compounds, Ta4ZTe4, with Z = Cr, Fe, Co, Ni, Al, or Si. The structure consists of Si-centered chains of antiprismatically stacked Ta squares that are edge bridged by Te. © 1990, American Chemical Society. All rights reserved.
