The title compound, [Pd(C6H4N2S2)(C18H15P)2], was obtained as a minor product from the reaction of trans-PdCl2(PPh3)2 with piperazine-1,4-dicarbothioic acid bis(pyridin-2-yl)amide. The PdII atom displays a slightly distorted square-planar PdP2S2 geometry with a bidentately coordinated pyridin-2-ylcarbonimidodithioate ligand and two triphenylphosphine molecules, coordinated in cis positions. The features weak π–π [centroid–centroid distance =3.7327(15) Å] and C–H⋯π interactions and contains an almost spherically shaped void of 50.4 Å3 per unit cell.

20 ml (10 -2 mol/L) DMF solution of piperazine-1,4-dicarbothioic acid bis-pyridin-2-ylamide was stirred with 20 ml (2x10 -2 mol/L) solution of PdCl2(PPh3)2 in chloroform. As a result of slow evaporation (1 month) several yellow prismatic crystals of the title compound were obtained from reaction mixture (yield ~5%).
All H atoms were placed in calculated positions with C–H = 0.95 Å and Uiso(H) = 1.2Uiso(C).
Structural investigation of palladium coordination compounds with carbothioamide derivatives has an actuality due to their potential biological activity (Garoufis et al., 2009). The current paper reports a structural study of a coordination compound obtained as a minor product as a result of the decomposition of the initially used organic ligand molecule in DMF solution.

of contains one molecule of the complex, in which palladium displays a slightly distorted square-planar PdP2S2 coordination geometry (Fig. 1). Mean deviation from the plane Pd1/P1/P2/S1/S2 is 0.0455 Å (maximum deviation for S1 = -0.0646 (5) Å). The values of Pd–P and Pd–S bond lengths correspond to those in related structures (Ahmed et al., 1977). S1–Pd1–S2 strongly deviates from 90° due to of the four-membered ring. The opposite angle P1–Pd1–P2 has a value of 99.77 (2)° that can be explained by repulsion of bulky phenyl rings of triphenylphosphine moieties. The organic ligand molecule coordinates to palladium bidentantly as a dianion. Two triphenylphosphine ligands coordinate to the palladium in a cis-conformation, although there is a trans-conformation in the initial reagent. The bonds C1–S1 and C2–S2 correspond to C–S single bonds (Allen et al., 1987). At the same time, C1—N1 shows a value of 1.275 (2) Å corresponding to a classical C=N double bond. The ligand molecule contains two planar fragments C1/N1/S1/S2 and N1/N2/C2–C6, creating a dihedral angle of 58.22 (8)°.

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. |

Structural investigation of palladium coordination compounds with carbothioamide derivatives has an actuality due to their potential biological activity (Garoufis et al., 2009). The current paper reports a structural study of a coordination compound obtained as a minor product as a result of the decomposition of the initially used organic ligand molecule in DMF solution.
The asymmetric unit of crystal structure contains one molecule of the complex, in which palladium displays a slightly distorted square-planar PdP2S2 coordination geometry (Fig. 1). Mean deviation from the plane Pd1/P1/P2/S1/S2 is 0.0455 Å (maximum deviation for S1 = -0.0646 (5) Å). The values of Pd–P and Pd–S bond lengths correspond to those in related structures (Ahmed et al., 1977). S1–Pd1–S2 strongly deviates from 90° due to steric strain of the four-membered ring. The opposite angle P1–Pd1–P2 has a value of 99.77 (2)° that can be explained by repulsion of bulky phenyl rings of triphenylphosphine moieties. The organic ligand molecule coordinates to palladium bidentantly as a dianion. Two triphenylphosphine ligands coordinate to the palladium in a cis-conformation, although there is a trans-conformation in the initial reagent. The bonds C1–S1 and C2–S2 correspond to C–S single bonds (Allen et al., 1987). At the same time, C1—N1 shows a value of 1.275 (2) Å corresponding to a classical C=N double bond. The ligand molecule contains two planar fragments C1/N1/S1/S2 and N1/N2/C2–C6, creating a dihedral angle of 58.22 (8)°. The crystal structure of the title compound shows a large number of weak π–π and C–H···π interactions and contains an almost spherically shaped void of 50.4 Å3 per unit cell (Fig. 2).
