In the title compound [Fe₂(C₂O₄)(C₈H₈N₄)₄](CH₃C₆H₄SO₃)₂·2.75H₂O, the two Fe^II ions have a highly distorted octahedral FeN₄O₂ environment formed by two bidentate triazole-based chelating ligands and a bis-bidentate oxalate bridging anion that connects the metal ions. Stabilization within the crystal structure is provided via a system of O—H⋯O and N—H⋯O hydrogen bonding, which determines the formation of a two-dimensional architecture along the a-axis direction.

Keywords: crystal structure; iron(II) complex; 1,2,4-triazole; oxalato-bridged complex; X-ray crystallography.

1. Chemical context

The study of coordination compounds based on substituted 1,2,4-triazoles and 3d and 4d transition metals allows the design of supramolecular structures that can find applications in various fields such as molecular magnetism, catalysis, electrochemistry or cluster engineering (Zhang et al., 2017 ; Zakharchenko et al., 2019 ; Chen et al., 2015 ; Petrenko et al., 2020 , 2021 ). The presence of the pyridine ring in such triazole systems leads to the formation of interesting isolated metal–organic frameworks that demonstrate promising magnetic properties, making them suitable for application as molecule-based magnets (Yao et al., 2015 ; Han et al., 2017 ; Li et al., 2015 ; Huang et al., 2015 ). Moreover, a combination of 3d⁴–3d⁷ metals with N-donor bridging ligands may form coordination compounds with switchable spin states (Aromí et al., 2011 ; Kucheriv et al., 2021 ). This phenomenon is called spin crossover. Changes in the external temperature, pressure, magnetic field, light radiation or the presence of a guest alters the magnetic, electrical, mechanical and optical properties significantly in these compounds (Gütlich & Goodwin, 2004 ). Therefore, the synthesis and crystallographic characterization of these complexes are of current interest.

On the other hand, the ability of the oxalate anion to generate homobinuclear complexes is well known (Craig et al., 2010 ; Selmi et al., 2021 ; Karimpour et al., 2013 ; Paine et al., 2007 ). The coordination chemistry of oxalato-bridged binuclear Fe^II complexes with pyridyl-triazole chelating ligands is less studied. A few examples with a similar type of ligand indicate that complexes of this kind possess interesting magnetic and oxidizing properties (de Ruiter et al., 2008 ; Oliveira et al., 2018 ). In order to continue research in this field and in the course of our studies dedicated to the investigation of triazoles and, in particular, 3-methyl-5-(pyrid-2-yl)-2H-1,2,4-triazole (metrzpy) (Zakharchenko et al., 2017 ; Zakharchenko, Khomenko, Doroschuk, Raspertova, Fesych et al., 2021 ; Zakharchenko, Khomenko, Doroshchuk, Raspertova, Shova et al., 2021 ), we report herein the synthesis and crystal structure of a new binuclear iron(II) complex with this ligand.

2. Structural commentary

The structure of the title compound is built up from dinuclear [Fe₂(metrzpy)₄(C₂O₄)]²⁺ complex cations, p-toluenesulfonate anions and co-crystallized water molecules in a 1:2:2.75 ratio. It crystallizes in the triclinic space group P $[\overline{1}]$ with two complex molecules per unit cell. Each iron(II) ion has an N₄O₂ coordination environment in a distorted octahedral geometry provided by two chelating metrzpy ligands in cis positions and a bidentate bridging oxalate anion (Fig. 1, Table 1). The reduced values of the angles subtended at the iron atom by the metrzpy and oxalate ligands are the main factors behind this distortion. The Fe—N and Fe—O bond lengths vary in the ranges 2.150 (3)–2.209 (3) Å and 2.123 (2)–2.171 (2) Å, respectively. The Fe1⋯Fe2 separation across the oxalate bridge of 5.576 (6) Å is in good agreement with previously reported values for other oxalate-bridged iron(II) complexes. The sets of coordinating atoms (O1/O2/N2/N6 for Fe1 and O3/O4/N10/N14 for Fe2) defining the mean equatorial planes are co-planar within 0.22 and 0.20 Å, while the displacement of the metal atom from these planes is 0.015 (1) and 0.037 (1) Å, respectively. The dihedral angle formed by each plane and the mean plane of the oxalate atoms is of 9.74 (6)° for Fe1 and 10.04 (7)° for Fe2.

3. Supramolecular features

All the species present in the structure are interconnected via a system of O—H⋯O and N—H⋯O hydrogen bonds (Table 2), which determines the formation of a two-dimensional architecture, as shown in Fig. 2. Further analysis has shown that the main crystal-structure motif consists of the parallel packing of 2D layers consolidated by the π–π stacking interactions observed between triazole and pyridine rings of adjacent cationic entities (Fig. 3) with a centroid-to-centroid distance of 3.746 (1) Å.

4. Database survey

A search of the Cambridge Structural Database (CSD, version 5.43, last update November 2021; Groom et al., 2016 ) gave 189 hits for the Fe₂(μ-C₂O₄) unit, the majority of which are iron(II)-based metal–organic coordination polymers. Besides them, there are several homobimetallic structures with an [FeN₄O₂] coordination environment: AVIMUN (Spek et al., 2004 ), LOZHOA (Oliveira et al., 2018), NOLSUF and NOLTAM (Gusev et al., 2019 ) and VIHCIZ (Paine et al., 2007). It must be noted that AVIMUN is a homologue of the title compound and contains a 3-ethyl-1,2,4-triazole fragment; however, it has a different packing and the crystal structure belongs to the monoclinic system.

A search for the structures of coordination compounds based on 3-methyl-5-(pyrid-2-yl)-2H-1,2,4-triazole revealed ten hits. Three of these structures represent our previous studies: CAMSUI (Zakharchenko, Khomenko, Doroschuk, Raspertova, Shova et al., 2021), IXIBID and IXIBOJ (Petrenko et al., 2021). The other structures correspond to mixed-ligand complexes with various metals, among them: NIYRAQ (Cao et al., 2014 ), QURBIQ (Guetlich & Schollmeyer, 2015 ), REWSOC (Cheng et al., 2007 ), SARQIO (Muller et al., 2013 ) and VESZOI (Buchanan et al., 1990 ).

5. Synthesis and crystallization

The triazole ligand was prepared according to a synthesis described in the literature (Zakharchenko et al., 2017). Single crystals of [Fe₂(C₂O₄)(metrzpy)₄](CH₃C₆H₄SO₃)₂·2.75H₂O were obtained by the liquid-to-liquid diffusion technique using a layering tube. The bottom was filled with Fe(CH₃C₆H₄SO₃)₂·6H₂O (50.6 mg, 0.1 mmol) in 2 ml of water. The middle was filled with a solution of 2 ml methanol/water (1:1) containing ascorbic acid (35.2 mg, 0.2 mmol). Then the top was filled with a solution of metrzpy ligand (32.0 mg, 0.2 mmol) in 2 ml of methanol. Afterwards, the tube was sealed with parafilm and light brown square-plate single crystals were formed within 3 days in relative high yield (ca 50%).

6. Refinement

Crystal data, data collection and structure refinement details are summarized in Table 3. All hydrogen atoms were placed geometrically and refined as riding, with C—H = 0.96 (CH₃), 0.93 Å (C_arom), N—H = 0.86 Å and O—H = 0.85–0.87Å, and with U_iso(H) = 1.2U_eq(C_arom) or 1.5U_eq(C-methyl). N-bound H atoms were refined with U_iso(H) = 1.2U_eq(N). The idealized OH₂ molecule was fixed using an AFIX 3, U_iso(H) = 1.5U_eq(O_water).

Special details top

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.
