title: 2,2'-[2,3-dihydro-2-(prop-2-enyl)-1H-isoindole-1,3-diylidene]bis(propanedinitrile)-tetrathiafulvalene (1/1), TCPI-TTF.
abstract: The title complex, C17H9N5*C6H4S4, contains pi-deficient bis(dinitrile) and TTF molecules stacked alternately in columns along the a-axis direction; the interplanar angle between the TTF molecule and the isoindolinyl C4N[C(CN)2]2 moiety is 1.21 (4) degrees. The N-allyl moiety in the TCPI molecule is oriented at an angle of 87.10 (10) degrees with respect to the five-membered C4N ring, and the four C[triple-bond]N bond lengths range from 1.134 (3) to 1.142 (3) A, with C-C[triple-bond]N angles in the range 174.3 (3)-176.9 (2) degrees. In the TTF system, the S-C bond lengths are 1.726 (3)-1.740 (3) and 1.751 (2)-1.763 (2) A for the external S-C(H) and internal S-C(S) bonds, respectively.
