Two organic conducting materials, where unusual aspects of their composition play important roles, are explored: beta''-(BEDT-TTF)2SF5XSO3 which exhibits superconductivity, or a metal-insulator transition (for X=CH2CF2 or CHF respectively), and tau-(P-S, S -DMEDT-TTF)2 (AuBr2) (AuBr2)y which exhibits a large, hysteretic, negative magnetoresistance. Detailed angular dependent magnetoresistance studies that allow a tomographic view of the electronic structure of these materials with increasing magnetic fields are presented.
