Abstract

In the title complex salt, [Pd(C₁₀H₈N₂)(C₁₂H₁₂N₂O₂)](CF₃SO₃)₂, the palladium(II) atom is fourfold coordinated by two chelating ligands, 2,2′-bipyridine and 4,4′-dimethoxy-2,2′-bipyridine, in a distorted square-planar environment. In the crystal, weak π–π stacking interactions between the 2,2′-bipyridine rings [centroid-to-centroid distances = 3.8984 (19) Å] and between the 4,4′-dimethoxy-2,2′-bipyridine rings [centroid-to-centroid distances = 3.747 (18) Å] contribute to the alignment of the complex cations in columns parallel to the b-axis direction.

Structure description

Bipyridine derivatives continue to be recognized as valuable ligands for the synthesis of new transition-metal complexes, including cobalt(II) (Kondori et al., 2021 ▸), ruthenium(II) (Benson et al., 2021 ▸; Maier et al., 2022 ▸), iron(II) (Karges & Gasser, 2020 ▸), copper(II) (Shchegolkov et al., 2021 ▸) and palladium(II) (Komlyagina et al., 2023 ▸) to mention a few. Recently, palladium(II) complexes containing 2,2′-bipyridine as ligand have shown significant cytotoxicity against HT-29 (colorectal adenocarcinoma), MCF-7 (breast), and HeLa (human squamous cervical adenocarcinoma) cancer cell lines (Tabrizi et al., 2020 ▸). As part of our research in this area, we describe herein the synthesis and structure of the title palladium(II) complex.

The asymmetric unit comprises one complex cation and two trifluoromethanesulfonate anions. The palladium(II) atom shows a distorted square-planar coordination environment defined by a bidentate 2,2′-bipyridine ligand and a bidentate 4,4′-dimethoxy-2,2′-bipyridine; trifluoromethanesulfonate ions sit in the outer coordination sphere, balancing the charge of the complex metal cation (Fig. 1 ▸). The Pd—N bond lengths are in good agreement with those in comparable square-planar 4,4′-dimethoxy-2,2′-bipyridine palladium(II) complexes currently available in the Cambridge Structural Database (CSD, version 5.45, Nov 2023; Groom et al., 2016 ▸): refcodes BEPVIF (Yang et al., 2022 ▸), WISQUO (Komlyagina et al., 2023 ▸); WISRAV (Komlyagina et al., 2023 ▸). The τ₄ descriptor value (Yang et al., 2007 ▸) of 0.22 reflects a significant distortion from a perfect square-planar coordination (τ₄ = 0). Numerical data for relevant bond lengths and angles are presented in Table 1 ▸.

In the extended structure, the complex packs into columns extending parallel to the b axis (Fig. 2 ▸). Contiguous pyridine rings show weak π–π stacking interactions, with centroid-to-centroid distances (Cg⋯Cg) alternating between 3.7472 (18) Å (between 4,4′-dimethoxy-2,2′-bipyridine ligands) and 3.8984 (19) Å (between 2,2′-bipyridine ligands), and offset distances of 1.641 and 1.769 Å, respectively (Fig. 3 ▸). No other significant supramolecular interactions are present in the crystal packing of the title compound.

Synthesis and crystallization

The title complex was prepared by adding Ag(CF₃SO₃) (0.0771 g, 0.300 mmol) to an acetonitrile suspension (40 ml) of [Pd(2,2′-bipyridine)Cl₂] (0.100 g, 0.300 mmol). The mixture was heated, with stirring, at 333 K for 2 h and then filtered using a PTFE syringe filter to remove the precipitated AgCl. 4,4′-Dimethoxy-2,2′-bipyridine (0.0649 g, 0.300 mmol) was added to the resulting solution and heated at 343 K to reduce the volume of the solution to 10 ml. X-ray diffraction quality crystals of the title complex were obtained by vapor diffusion of ether over the resulting concentrated acetonitrile solution.

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