The title compound, bis­(μ-2-carb­oxy-4-nitro­benzoato-κ2O1:O1′)bis­[bis­(1,10-phenanthroline-κ2N,N′)cobalt(II)] bis­(2-carb­oxy-4-nitro­benzoate) tetra­hydrate, [Co2(C8H4NO6)2(C12H8N2)4](C8H4NO6)2·4H2O, comprises a centrosymmetric dinuclear cobalt(II) complex dication, two hydrogen 4-nitro­phthalate anions and four water mol­ecules of crystallization. The two CoII atoms are linked by two μ-hydrogen 4-nitro­phthalato ligands, generating a centrosymmetric dinuclear unit. Each cobalt(II) centre adopts a distorted octa­hedral coordination geometry defined by four N atoms from two chelating 1,10-phenanthroline ligands and two O atoms from two symmetry-related bridging hydrogen 4-nitro­phthalate ligands. In the crystal, O—H⋯O and C—H⋯O hydrogen bonds link the ionic components into a three-dimensional supra­molecular framework, which is further reinforced by aromatic ππ stacking inter­actions between neighbouring phenanthroline and hydrogen 4-nitro­phthalate rings, with centroid-to-centroid separations ranging from 3.501 (5) to 3.687 (4) Å. Hirshfeld surface analysis shows that O⋯H/H⋯O contacts make the largest contribution (38.1%) to the crystal packing, confirming the dominant role of hydrogen bonding in consolidating the crystal structure.

1. Chemical context

Mixed-ligand cobalt(II) complexes containing aromatic N-donor and polycarboxyl­ate ligands continue to attract attention because of their structural diversity and supra­molecular assembly patterns (Sammes & Yahioglu, 1994View full citation; Bencini & Lippolis, 2010View full citation). In particular, 1,10-phenanthroline commonly forms stable chelating coordination environments, whereas nitro­phthalate ligands exhibit versatile coordination modes and hydrogen-bonding capabilities. As part of our ongoing studies of cobalt(II) complexes containing mixed N- and O-donor ligands, the title dinuclear complex incorporating 1,10-phenanthroline and hydrogen 4-nitro­phthalate ligands was synthesized and characterized by single-crystal X-ray diffraction analysis.

2. Structural commentary

The mol­ecular structure of the title compound is shown in Fig. 1[link]. The complex crystallizes in the triclinic space group PMathematical equation. The asymmetric unit comprises one CoII atom, two chelating 1,10-phenanthroline ligands, one μ2-bridging hydrogen 4-nitro­phthalate ligand, one uncoordinated hydrogen 4-nitro­phthalate anion and two solvent oxygen atoms (O1W and O2W) corresponding to highly disordered water mol­ecules. The complete centrosymmetric dinuclear complex dication is generated by inversion symmetry.

Each CoII centre adopts a distorted octa­hedral CoN4O2 coordination geometry defined by four nitro­gen atoms from two chelating 1,10-phenanthroline ligands and two oxygen atoms from two symmetry-related hydrogen 4-nitro­phthalate ligands. The Co—O bond length is 2.070 (4) Å, while the Co—N bond distances range from 2.126 (4) to 2.169 (4) Å (Table 1[link]). The cis angle O5—Co1—O6i is 91.94 (13)°, while the trans angles N3—Co1—N5 and O5—Co1—N4 are 173.52 (16) and 171.16 (16)°, respectively, indicating only a slight distortion from an ideal octa­hedral geometry.

The coordinated hydrogen 4-nitro­phthalate ligand adopts a μ2-κO:κO′ bridging coordination mode, linking two symmetry-related cobalt(II) centres into a centrosymmetric dinuclear complex dication with an intra­molecular Co⋯Co separation of 4.795 (2) Å. Within the coordinated carboxyl­ate group, the C—O bond distances [1.254 (6) and 1.273 (6) Å] are consistent with electron delocalization, whereas the uncoordinated carb­oxy­lic group exhibits unequal C—O bond lengths [1.237 (7) and 1.326 (7) Å], confirming its protonated nature.

The coordinated 1,10-phenanthroline ligands are essentially planar and provide extended aromatic surfaces that participate in significant inter­molecular ππ stacking inter­actions, which, together with the hydrogen-bonding network, contribute to the cohesion of the crystal packing and the formation of a three-dimensional supra­molecular architecture.

3. Supra­molecular features

The crystal packing is governed by a combination of classical O—H⋯O and weak C—H⋯O hydrogen bonds (Table 2[link]), together with significant aromatic ππ stacking inter­actions (Fig. 2[link]). The uncoordinated hydrogen 4-nitro­phthalate anions act as both hydrogen-bond donors and acceptors, whereas the solvent water oxygen atoms serve as hydrogen-bond acceptors. Collectively, these inter­actions link the centrosymmetric dinuclear complex dications, hydrogen 4-nitro­phthalate anions and solvent species into a three-dimensional supra­molecular architecture.

Several significant ππ stacking inter­actions are observed between the aromatic rings of the coordinated 1,10-phenanthroline ligands and the hydrogen 4-nitro­phthalate ligands. The shortest inter­action occurs between the pyridine ring of one 1,10-phenanthroline ligand (N4/C9–C12/C20; Cg5) and the benzene ring of a hydrogen 4-nitro­phthalate ligand (C1–C6; Cg7), with a centroid-to-centroid distance of 3.500 (5) Å, an inter­planar angle of 0.6° and a slippage of 1.03 Å, indicating an almost ideal face-to-face arrangement. Additional significant contacts are observed: Cg3⋯Cg3i [3.600 (4) Å, 0.0°, 1.19 Å], Cg7⋯Cg8i [3.609 (5) Å, 1.4°, 1.42 Å] and Cg9⋯Cg10i [3.687 (4) Å, 2.7°, 1.18 Å] [Cg3, Cg7, Cg8, Cg9 and Cg10 are the centroids of the N2/C26–C29/C31, C1–C6, C12–C15/C19/C20, C23–C26/C30/C31 and C32–C37 rings, respectively; symmetry code: (i) −x + 2, −y + 1, −z + 1]. These geometrical parameters indicate efficient overlap of the aromatic π systems and contribute significantly to the cohesion of the crystal packing.

4. Hirshfeld surface analysis

Hirshfeld surface analysis and the corresponding two-dimensional fingerprint plots were generated using CrystalExplorer21.5 (Spackman et al., 2021View full citation) to investigate the inter­molecular inter­actions responsible for the crystal packing. The Hirshfeld surface mapped over dnorm and the associated fingerprint plots are shown in Figs. 3[link] and 4[link], respectively.

The O⋯H/H⋯O contacts make the largest contribution to the Hirshfeld surface (38.1%), confirming that hydrogen bonding involving the carboxyl­ate, carb­oxy­lic acid and nitro oxygen atoms plays the dominant role in consolidating the crystal structure. H⋯H contacts account for 21.7% of the surface, reflecting the contribution of van der Waals inter­actions, whereas C⋯H/H⋯C contacts contribute 13.9%, indicating numerous weak inter­molecular C⋯H contacts within the crystal packing. Smaller contributions arise from O⋯C/C⋯O (6.1%), O⋯O (4.2%) and O⋯N/N⋯O (1.2%) contacts.

The Hirshfeld surface analysis is consistent with the crystallographic study, demonstrating that the crystal packing is governed primarily by classical hydrogen bonding, supplemented by weak inter­molecular contacts and significant aromatic ππ stacking inter­actions, which together generate the observed three-dimensional supra­molecular architecture.

5. Database survey

A search of the Cambridge Structural Database (CSD, Version 2025.3.1, update of February 2026; Groom et al., 2016View full citation) revealed several cobalt(II) complexes containing the 4-nitro­phthalate ligand. Representative examples include HOJHOF (Li et al., 2014View full citation), JUYREC and JUYRIG (Wang et al., 2015aView full citation), and LUDJUR (Yin & Li, 2015View full citation), in which the 4-nitro­phthalate ligand adopts various bridging coordination modes and gives rise to one-dimensional or higher-dimensional coordination architectures.

A separate search for cobalt(II) complexes containing both 1,10-phenanthroline and aromatic polycarboxyl­ate ligands identified several structurally related dinuclear complexes, including AJIYID (Wang et al., 2015bView full citation) and HUBCOY and HUBCUE (Wang et al., 2015cView full citation). In these compounds, the CoII centres exhibit distorted octa­hedral coordination geometries defined by nitro­gen atoms from chelating 1,10-phenanthroline ligands and oxygen atoms from bridging carboxyl­ate groups.

The title compound displays structural features characteristic of both families, combining a centrosymmetric dinuclear cobalt(II) core bridged by hydrogen 4-nitro­phthalate ligands with chelating 1,10-phenanthroline ligands. A search of the current version of the CSD revealed no previously reported cobalt(II) complex containing both 1,10-phenanthroline and 4-nitro­phthalate ligands. To the best of our knowledge, the present structure therefore represents the first crystallographically characterized example of this type.

6. Synthesis and crystallization

The title compound was synthesized from cobalt(II) chloride hexa­hydrate, 4-nitro­phthalic acid and 1,10-phenanthroline using a molar ratio of 1:1:0.5. 4-Nitro­phthalic acid (1.00 mmol, 0.211 g) was dissolved in N,N-di­methyl­formamide (DMF), 1,10-phenanthroline (0.50 mmol, 0.090 g) in ethanol, and cobalt(II) chloride hexa­hydrate (1.00 mmol, 0.238 g) in distilled water. The solutions of 4-nitro­phthalic acid and cobalt(II) chloride hexa­hydrate were mixed and stirred magnetically for 20 min, after which the 1,10-phenanthroline solution was added dropwise. The resulting reaction mixture was stirred at 333 ± 0.5 K for a further 20 min. The clear solution was then left to stand at room temperature in a loosely covered vessel at pH ≃ 6.0. After 12 days, bright-red prismatic crystals suitable for single-crystal X-ray diffraction analysis were obtained. The crystals were collected by filtration and dried in air.

7. Refinement

Crystal data, data collection and structure refinement details are summarized in Table 3[link]. Hydrogen atoms bonded to carbon atoms were placed in calculated positions and refined using a riding model, with C—H = 0.93 Å and Uiso(H) = 1.2Ueq(C). The hydrogen atoms of the carb­oxy­lic acid groups were located in difference-Fourier maps and subsequently refined using a riding model with O—H = 0.82 Å and Uiso(H) = 1.5Ueq(O). The nitro group of the coordinated hydrogen 4-nitro­phthalate ligand is disordered over two orientations and was refined using a split-atom model with refined site-occupancy factors of 0.51 (1) and 0.49 (1). Similarity restraints were applied to the N—O bond distances and anisotropic displacement parameters of the disordered atoms. Two solvent oxygen atoms (O1W and O2W), assigned to water mol­ecules of crystallization, were located in difference-Fourier maps and refined anisotropically. The corresponding hydrogen atoms could not be identified reliably in difference-Fourier maps and were therefore not included in the refinement.

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.
