4,5-Bis(benzylthio)-1,3-dithiole-2-thiones, [(p-XC6H4CH2)(p-XC6H 4CH2)dmit: X = Y = OMe (2); X = OMe, Y = NO2 (3); and X = NO2] (4)] have been prepared from benzyl chlorides and [NEt4]2[Zn(dmit)2]. Isostructural compounds, 2 and 3, crystallize in the triclinic space group P1 (Z = 2) with a = 5.2920(10), b = 10.537(2), c = 18.961(4) A, α = 102.79(3), β = 96.33(3), γ = 98.67(3)° for 2; a = 5.292(8), b = 10.528(12), c = 19.01(2) A, α = 102.74(9), β = 96.26(11), γ = 98.56(11)° for 3. Compound 4 also crystallizes in the space group P1 (Z = 4), with a = 9.296(8), b = 13.993(18), c = 16.186(4) A, α = 106.68(3), β = 89.63(3), γ = 99.38(6)°. Molecular differences between 2 and 3, on one hand, and 4, on the other, arise in the disposition of the aryl rings relative to the dmit group. Short S...S contacts in 2 of 3.320(2) A [S3...S3i (symmetry operation: i: -x + 1, -y + 1, -z)] and in 3 of 3.314(5)A [S3...S3i (symmetry operation: i: -x + 1, -y, -z + 1)] link molecules into pairs. In 4, an S5A...S2B contact of 3.516(5) A links two independent molecules, A and B, into bimolecular units, which are further connected into chains by S2A...S5Bi contacts (symmetry operation: i: x, y, z - 1) at 3.569(5) A. C-H...O hydrogen bonds are also present in 3 and 4.

The syntheses of the new TTF derivatives 1a-g (table 2) and of the thiones 2a-k (table 1) are described.Influences of the substituents R on the dimerization of the thiones 2 and on the charge transfer interactions are noted.The conductivity of electric currency of some of the isolated charge transfer complexes containing TCNQ, TCNE and bromine is described.
