The asymmetric unit of the title complex, [Co(NO₃)(C₁₀H₈N₂)(H₂O)₃]Cl, consists of a chloride anion and a complex cation, which is built on a monodentate nitrate anion, three water molecules and one bidentate 2,2′-bipyridine molecule, coordinated to a Co^II cation, in a distorted octahedral geometry. The water molecules are arranged in a facial geometry, and serve as donors for hydrogen bonding. Acceptor sites in the crystal are chloride ions and one O atom of the coordinating nitrate ion. A three-dimensional framework is formed, based on O—H⋯O and O—H⋯Cl contacts.

Keywords: crystal structure; cobalt; nitrate; 2,2′-bipyridine; supramolecular interactions.

Structure description

As a component of several enzymes, vitamins, proteins and nucleic acids, pyridine derivatives have a main role in many biological systems. Some complexes containing 2,2′-bipyridine (bipy) have been reported to present antibacterial activity (El-Hamid et al., 2017 ; Lu et al., 2015 ; Segura et al., 2014 ), including cobalt complexes (Buriez et al., 2006 ; Gu et al., 2017 ). It can be expected that the combination of the high bactericidal activity of bipy and a cobalt cation may lead to a compound of interest. In this dynamic, we have initiated the study of the interaction between [Na₃Co(NO₂)₆], dimethylammonium chloride and bipy. The complex reported herein results from a redox process over the cobalt complex used as starting material, when the reaction is carried out in acetone and in a non-controlled atmosphere: the nitrite anion NO₂⁻ behaves as a reducing agent to reduce Co^III to Co^II, and is in turn oxidized to form nitrate ions NO₃⁻. A stable cation complex [Co(bipy)(OH₂)₃(NO₃)]⁺ is then formed, which crystallizes as a chloride salt in presence of [NH₂Me₂]⁺Cl⁻.

The asymmetric unit of the title compound (Fig. 1) consists of a chloride anion and a complex cation containing a chelating 2,2′-bipyridine molecule, a monocoordinating nitrate anion and three water molecules to complete the octahedral coordination sphere around the cobalt cation. Coordination bond lengths are in the small range 2.0300 (16)–2.1769 (15) Å, indicating that the ligand field should be small enough to stabilize a high spin 3d⁷ metal configuration, reflected in the limited Jahn–Teller tetragonal distortion. Using the octahedral symmetry measure defined by Alvarez et al. (2002 ), S(O_h) = 5.39Δ² − 0.33|Δ|, where Δ is the difference between long and short distances, we compute S(O_h) = 0.07 for the cation, close to the measure expected for an ideal octahedral field, S(O_h) = 0. The coordinating water molecules have a facial geometry, with the longest Co—OH₂ bond displayed by the axial water molecule O1 (Abboud et al., 1996 ; Johnson et al., 2015 ). The nitrate ion is placed trans to this water molecule, forming an angle O1—Co1—O14 of 170.47 (7)°. The equatorial plane includes the chelating bipy ligand and two water molecules, at normal distances (Xiao, 2006 ; Gong et al., 2012 ). The planarity of this [CoO₂N₂] core is confirmed by the sum of the four cis angles, 360.0 (3)°. The distortion from the octahedral symmetry results essentially from the bipy bite angle, N1—Co1—N12 = 77.37 (6)°. The metal is displaced by 0.04 Å from the equatorial mean plane. A similar arrangement was observed with other cations [M(bipy)(OH₂)₃(NO₃)]⁺ using different transition metals, M = Mn (Zhang et al., 2002 ), M = Ni (Walmsley et al., 1989 ; Rujiwatra et al., 2012 ), M = Cu (Mathews & Manohar, 1991 ) and M = Zn (Harrowfield et al., 2017 ).

The structure of the complex cation and the anion in the title compound, with displacement ellipsoids for non-H atoms at the 30% probability level.

Coordinating water molecules are oriented in such a way that all O—H groups serve as donors to form weak hydrogen bonds with chloride ions and atom O16 of the nitrate ion (Table 1). Each complex cation is then directly linked to four neighbours through intermolecular O—H⋯O bonds, and the supramolecular structure is extended to a three-dimensional framework through R₄²(8) ring motifs based on O—H⋯Cl bonds (Fig. 2). The relative orientation of the cations in the crystal resulting from this supramolecular structure does not prevent π–π interactions between bipy ligands: two cations related by inversion have their bipy parts placed parallel, with a separation between the mean planes of 3.375 Å.

Synthesis and crystallization

All chemicals were purchased from Aldrich Company and used as received. Sodium hexanitrocobaltate(III) [Na₃Co(NO₂)₆] (125 mg, 0.309 mmol), dimethylammonium chloride (25 mg, 0.309 mmol) and 2,2′-bipyridine (48 mg, 0.309 mmol) were mixed together at room temperature in slightly hydrated acetone. The resulting solution was stirred for about two h at 303 K. After a week of slow evaporation at room temperature, orange crystals suitable for X-ray crystallographic analysis were obtained.

Refinement

Crystal data, data collection and structure refinement details are summarized in Table 2. Intensities were collected at high resolution [(sinθ)/λ = 0.92 Å⁻¹; d = 0.54 Å].

Special details top

Refinement. H atoms of the bipy ligand were placed in calculated positions and refined as riding to their carrier C atoms, with U_iso = 1.2 U_eq(carrier C). In contrast, water H atoms were refined with free coordinates and free U_iso displacement parameters. O—H bond lengths converged to acceptable values in the range 0.73 (3)–0.85 (4) Å.
