Abstract

A radical cation salt composed of an organic donor, BEDT-TTF^1.0+, and a one-dimensional inorganic anion, [Fe(C₂O₄)Cl₂^-]_n, was obtained by electrocrystallization, and was identified as a semiconductor with values of σ_300K = 3.0 × 10^-5 S cm^-1. Spin-canted antiferromagnetic long-range ordering was observed at 5.5 K from ZFCM/FCM/RM measurement and confirmed using AC measurement.
