The crystal structure of orthorhombic CuTe, also known as the mineral Vulcanite, can be described as a strongly distorted a-PbO structure of corrugated copper layers alternating with linear, equidistant telluride chains along [001] (figure 1). According to theoretical calculations, the telluride

chains could undergo a Peierls-like distortion [1] which, until now, has not been observed experimentally [2].
