Abstract

We have found the true stoichiometry of the phase first reported as Fe0.25Nb0.75Se12, and later as FeNb3Se10, to be Fe1+xNb3-xSe10, with 0.25x0.40. Compounds with the FeNb3Se10 structure type are relatively rare among transition-metal selenides. We report the synthesis and temperature-dependent magnetic susceptibility and resistivity of the new compounds Fe1.33Ta0.67Nb2Se10 and Fe1-yV1+yNb2Se10, with 0.0y0.5. The magnetic susceptibility and Mössbauer-effect measurements on Fe1+xNb3-xSe10 are dominated by the Fe-Nb disorder on the zigzag octahedral chains.
