Abstract

The asymmetric unit of the title salt, [Co(C₂₀H₁₄N₄S)(H₂O)₂](NO₃)₂, comprises a [Co(C₂₀H₁₄N₄S)(H₂O)₂]²⁺ cation and two NO₃ ⁻ anions. In the complex, [Co(C₂₀H₁₄N₄S)(H₂O)₂]²⁺ cation, the tetradentate 6,6′-sulfanediylbis(2,2′-bipyridine) ligand coordinates to the Co^II cation in the equatorial positions, while two water molecules occupy the axial positions, forming a compressed octahedral CoN₄O₂ coordination sphere. The NO₃ ⁻ anions are linked to the [Co(C₂₀H₁₄N₄S)(H₂O)₂]²⁺ cations via O—H⋯O hydrogen bonds, yielding a layered arrangement parallel to (001).

Chemical context

The control of the molecular structure of coordination compounds is an important task in crystal engineering. It is well known that organic ligands play a significant role in determining the crystal structure of coordination complexes. For example, bidentate 2,2′-bipyridine or its derivatives are common ligands that can be employed to assemble functional compounds (Zhang et al., 2014 ▸; Kamdar et al., 2016 ▸; Pal et al., 2014 ▸). Linking two 2,2′-bipyridine units through a suitable atom leads to a tetradentate ligand (Knight et al., 2010 ▸) and, more importantly, the distance of the two 2,2′-bipyridine moieties can then be controlled by the type and size of the bridging atom. As a consequence, the coordination geometry of the metal cation can be affected. graphic file with name e-73-00993-scheme1.jpg

Recently, we obtained the title salt, [Co(C₂₀H₁₄N₄S)(H₂O)₂](NO₃)₂, using a tetradentate ligand in which two 2,2′-bipyridine moieties are linked by a sulfur atom. Herein, we report the crystal structure of this cobalt complex.

Structural commentary

The asymmetric unit of the title salt (Fig. 1 ▸) is composed of a [Co(C₂₀H₁₄N₄S)(H₂O)₂]²⁺ cation and two NO₃ ⁻ anions. The cobalt(II) atom of the complex [Co(C₂₀H₁₄N₄S)(H₂O)₂]²⁺ cation features a compressed octahedral CoN₄O₂ coordination sphere with the N atoms of the tetradentate ligand in equatorial positions and two water molecules located at the trans axial sites. The corresponding Co—O bond lengths are 2.0444 (18) Å and 2.0821 (17) Å, which are obviously shorter than the equatorial Co—N bond lengths [2.1213 (18) −2.1574 (18) Å]. These coordination bond lengths indicate that the Co^II cation is in a high-spin state at 123 K, comparable with other high-spin Co^II complexes (Li et al., 2016 ▸; Knight et al., 2010 ▸; Suckert et al., 2017 ▸; Zhong et al., 2008 ▸; Hathwar et al., 2017 ▸). The O—Co—O angle is almost linear at 178.59 (7)°. The four equatorial N atoms and the Co^II cation are approximately coplanar, with the largest deviation from the least-squares plane being 0.039 Å for N3.

In a similar Co^II complex with the 6,6′-sulfanediylbis(2,2′-bipyridine) ligand replaced by the tetradentate ligand bis(2,2′-bipyrid-6′-yl)ketone (Knight et al., 2010 ▸), the Co^II cation is slightly convex (0.098 Å) from the plane formed through four coordination N atoms. The Co—O bond lengths of the two axial sites are significantly different at 2.075 (4) Å for that in the convex site and 2.118 (4) Å for that in the concave site. The corresponding O—Co—O bond angle deviates more distinctly from linearity with a value of 172.46 (17)°. The structural differences between the title complex and the similar reported compound are ascribed to the bridging atom between the two 2,2′-bipyridine moieties, i.e. an S atom in the title complex versus a C atom of a keto group in the related compound. The bridging bonds [C—S: 1.761 (2) and 1.764 (2) Å] of the title complex are longer than those [C—C: 1.496 (10) and 1.500 (10) Å] in the related complex.

Supramolecular features

The coordinating water molecules act as proton donors, forming O—H⋯O hydrogen bonds with the NO₃ ⁻ anions and leading to an extended layer structure parallel to (001) for the title complex (Fig. 2 ▸). For these hydrogen bonds, the O⋯O distances are in the range of 2.688 (2)–2.789 (2) Å, indicating they are of medium strength (Table 1 ▸), and are comparable with other hydrogen bonds formed between coordinating water molecules and NO₃ ⁻ anions (Kurdziel et al., 2000 ▸; Kunz et al., 2007 ▸; Wang et al., 2012 ▸). There are no intermolecular π–π interactions in the molecular packing of the title complex.

Synthesis and crystallization

The ligand 6,6′-sulfanediylbis(2,2′-bipyridine) was synthesized by a method analogous to that for the preparation of 2,2′-sulfanediylbis(1,10-phenanthroline) (Krapcho et al., 2007 ▸). The title complex was obtained as follows: An ethanolic solution (10 ml) of Co^II(NO₃)₂·6H₂O (29.1 mg, 0.1 mmol) was added to a ethanolic solution (10 ml) of 6,6′-sulfanediylbis(2,2′-bipyridine) (34.4 mg, 0.1 mmol), which afforded a light-yellow solution, which was stored at ambient conditions. Yellow crystals of the title compound were obtained by slow evaporation of the solvent, yield: ca. 50%.

Refinement

Crystal data, data collection and structure refinement details are summarized in Table 2 ▸. All hydrogen atoms bound to carbon atoms were placed geometrically, with C—H = 0.93 Å and with U _iso(H) = 1.2U _eq(C). The hydrogen atoms of water molecules were found from difference-Fourier maps and their O—H bond lengths were normalized to 0.82 Å and refined with a common U _iso(H) parameter.

Special details

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.
