Comment top

Metal dithiolene complexes have been widely investigated as molecular conductors and superconductors. Several superconductors (Brossard et al., 1986; Cassoux et al., 1991; Kobayashi et al., 1987; Tajima et al., 1993) and single-component molecular metals (Tanaka et al., 2001) involving dithiolene complexes have been discovered to date. We have synthesized the title palladium dithiolene complex, (I), derived from 2,3-dicyano-5,6-dimercaptopyrazine ligand (Tomura et al., 1994). The ligand is expected to extend the π-conjugation of the complex resulting in decreased Coulombic repulsion (Belo et al., 1999, 2004; Nomura et al., 2009; Rabaça & Almeida, 2010). Intermolecular interactions caused by S···S and S···N heteroatom contacts may increase the dimensionality in the solid state (Yamashita & Tomura, 1998). We report here the molecular and crystal structures of (I).

In the complex (I) the dianion molecule is located on an inversion center. The molecular structure of the dianion is shown in Fig. 1. The dianion is a flat molecule with an r.m.s. deviation of 0.034 (8) Å of fitted atoms from the least-squares plane. The central Pd atom has a square-planar coordination geometry and the Pd1—S1 and Pd1—S2 distances and the S1—Pd1—S2 angle are 2.276 (3), 2.294 (3) Å and 89.39 (10)°, respectively. These values are comparable to those found in bis(tetra-n-butylammonium) bis(4,5-dicyanobenzene-1,2-dithiolato-S,S')palladium(II) complex (Alves et al., 2004). Fig. 2 shows the packing diagram of (I) viewed along the a axis. The dianion molecules form a layered structure with an interlayer distance of 6.5 Å. The tetra-n-butylammonium cations are inserted between the layers.

Experimental top

The title compound (I) was synthesized according to the literature method (Tomura et al., 1994). Orange crystals of (I) suitable for X-ray analysis were grown from an acetone solution.

Special details top

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
