The layered ternary tellurides NbNiTe 5 , TaNiTe 5 , TaPtTe 5 and NbPdTe 5 are all metallic, but the conductivity of the latter is between one and two orders of magnitude smaller. A tight binding study of the electronic structure of these phases suggests that the large conductivity difference results from the different Te···Te interlayer interactions and the Te → M (M = Nb, Ta) electron transfer that they induce.
