Magnetic properties of organic charge transfer salts Ag(DX) 2 (DX = 2,5-dihalogeno-N,N'-dicyanoquinonediimine; X = Cl, Br, I) were modified by UV irradiation from paramagnetism to diamagnetism in an irreversible way. The temperature dependence of susceptibility revealed that such change in magnetic behavior could be continuously controlled by the duration of irradiation. The observation with scanning electron microprobe revealed that the original appearance of samples, e.g. black well-defined needle-shaped shiny single crystals, remained after irradiation irrespective of the irradiation conditions and the duration. Thermochemical analysis and X-ray diffraction study demonstrated that the change in the physical properties were due to (partial) decomposition of Ag(DX) 2 to AgX, which was incorporated in the original Ag(DX) 2 lattices. Because the physical properties of  Corresponding author: tnaito@sci.hokudai.ac.jp 2 low-dimensional organic conductors are very sensitive to lattice defects, even a small amount of AgX could effectively modify the electronic properties of Ag(DX) 2 without making the original crystalline appearance collapse.

“…All Ag(DX) 2 (X = Cl, Br, I) are known to be isomorphous [22,23,[32][33][34][35][36][37][38][39][40][41][42] from X-ray measurements of their lattice parameters, yet their full structural analyses (atomic parameters) have not been reported.…”

“…328 Despite their regular stacks, these salts present some electronic (Mott) localization and may become electrical insulators well above any magnetic or Spin-Peierls phase transition. 329 This remark emphasizes the role of 1/4 Umklapp terms on the 1D Mott localization which is presently actively discussed in the Fabre series. 161 Another strongly localized quarter filled system, closer to the Bechgaard salts, has recently been published: (EDTTTF-CONMe 2 ) 2 AsF 6 , where the donor is a tertiary amide-functionalized ethylene-dithio-tetrathiafulvalene.…”
