Structural Characterization of the Charge-Transfer Complex Formed by Bis (propene-3-thione-1-thiolato) platinum (II) and Tetracyanoquinodimethane, (C3H3S2)2Pt-C12H4N4
Abstract
The crystal and molecular structure of the charge-transfer complex formed by bis(propene-3-thione-1-thiolato)platinum(II) and 7,7,8,8-tetracyanoquinodimethane has been determined from three-dimensional x-ray counter data. The material crystallizes in the triclinic space group P1 with one formula unit in a cell of dimensions a = 8.744 (5) Å, b = 9.488 (2) Å, c = 6.156 (3) Å,α = 92.10 (2)°, β = 102.73 (2)°, and γ = 105.19 (3)°. Least-squares refinement of the structure has led to a final R factor of 0.037 using 3683 independent observations. The structure consists of alternate donor and acceptor molecules stacked coplanar to each other in columns along the a axis. The mean interplanar spacing of 3.42 Å and the geometry of the TCNQ molecule suggest that the degree of charge transfer is slight. The geometry about the platinum atom is distorted square planar, with Pt-S distances of 2.282 (1) and 2.278 (1) Å. © 1977, American Chemical Society. All rights reserved.
