Abstract

Superlattice spots observed by X-ray and electron diffraction in the tetragonal, metallic, quasi-one-dimensional compounds NbTe4and TaTe4are interpreted in terms of charge-density waves. It is shown that three slightly different types of columns occur in the crystals. In NbTe4at room temperature two types of chains have incommensurate distortions with wavevectors q1=(0, 0, 0.311c*) and q2=(0.5a*, 0.5b*, 0.344c*): the third type has a very weak distortion with q3=(0.5a*, 0,1/3c*). The wavevectors for TaTe4are as above except that the component along the metal chain is exactly1/3c* in each case. The vectors q1and q2are independent of temperature but can be varied by substitution of Ta for Nb. These are structurally the simplest inorganic crystal structures in which CDW have been observed and are the only reported crystals in which three CDW coexist.
