Cover Story: The α-(Per)2[M(mnt)2] compounds are a unique isostructural family of two-chain solids, containing both conducting perylene chains and anionic chains, that can be either paramagnetic in (M = Pt), or diamagnetic in (M = Au). The electrical transport and magnetic properties of the solid solutions (Per)2[PtxAu(1−x)(mnt)2] were investigated, probing the effects of paramagnetic [Pt(mnt)2] centers in the diamagnetic chains, and effects of breaking the paramagnetic chains with diamagnetic centers for the low and high Pt range of concentrations. An additional β-phase was found to be composed of ordered layers with segregated donors and anion stacks alternating with disordered layers. View this paper
