Abstract

The structural representation of mutually incommensurate composite crystal, (BiS)~x~ TS~2~ (T = Ti, V, Nb and Ta), with layered substructures has been described by superspace group approach. The incommensurate composite structures of (BiS)~x~ TS~2~ have been successfully characterized by the single‐crystal X‐ray‐diffraction method. Temperature dependences of in‐plane electrical resistivity of single composite crystals of (BiS)~x~ TS~2~ have been obtained by a standard d.c. four probe method in the range of 1.7–300 K. It has been found that the electronic transport properties of (BiS)~x~ TS~2~ compounds show metallic behavior below room temperature. (© 2006 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
