Abstract

New metallic triclinic (1) and monoclinic (2) crystals of the (BEDT-TTF)4AI[MIII(C2O4)3]G family of organic molecular conductors have been prepared: α-“pseudo-κ”-(BEDT-TTF)4Kx(H3O)1–x[GaIII(C2O4)3]·1,2-C6H4Br2 (x ≈ 0.45) (1) and β″-(BEDT-TTF)4Kx(H3O)1–x[GaIII(C2O4)3]·PhBr (x ≈ 0.33) (2). The triclinic crystals belong to a quite rare type of bilayered radical ion salts and contain alternating BEDT-TTF layers with two distinct packing motifs (α- and “pseudo-κ”). The monoclinic crystals contain one kind of BEDT-TTF radical cation layers. The crystal structure, transport, and magnetotransport properties of 1 and 2 have been studied. The Shubnikov–de Haas (SdH) oscillations were found in both phases. The structure and properties of 1 and 2 are compared with another similar phase with M = FeIII.
