%X The synthesis, crystal structure, and conductivity of a solvent-included ternary charge-transfer salt (BEDT-TTF) 2GaCl 4(C 6H 5Cl) 0.5 ( 1) is described and interpreted. Electrochemical oxidation of neutral bis(ethyelenedithio)-tetrathiafulvalene (BEDT-TTF) in the presence of (Me 4N)Ga(C 2O 4)Cl 2 in a mixture of C 6H 5Cl and C 2H 5OH yields crystals of 1. Compound 1 crystallized as a monoclinic C 2/c space group with cell parameters: a = 47.0615(4) £¿, b = 6.7895(1) £¿, c = 31.6297(4) £¿, ¦Â = 132.064(1)¡ã, V = 7503.0(2) £¿ 3, Z = 8 at 293£¿K and a = 46.4767(5) £¿, b = 6.7398(1) £¿, c = 31.0778(4) £¿, ¦Â = 131.630(1)¡ã, V = 7267.4(2) £¿ 3, Z = 8 at 120 K. The formal charge of the donor molecule was assigned as +0.5 from bond lengths in the TTF core. The donor molecules stack with C¨D¡¤¡¤¡¤S contacts along the c direction and side-to-side S ¡­S contacts along the b direction to form a two-dimensional donor layer on the bc plane. In the anion sheet, C 6H 5Cl chain is sandwiched by two GaCl 4 £¿ chains with Cl ¡­Cl contacts. Compound 1 shows semiconductive behavior with E a = 124 meV between room-temperature and 150 K and ¦Ò 300K = 1 S¡¤cm £¿1.
