Reaction between equimolar amounts of 3,3,3′,3′-tetraethyl-1,1′-(furan-2,5-dicarbonyl)bis(thiourea) (H₂L) and CuCl₂·2H₂O in methanol in the presence of the supporting base Et₃N gave rise to a neutral dinuclear complex bis[μ-3,3,3′,3′-tetraethyl-1,1′-(furan-2,5-dicarbonyl)bis(thioureato)]dicopper(II) dichloromethane disolvate, [Cu₂(C₁₆H₂₂N₄O₃S₂)₂]·2CH₂Cl₂ or [Cu₂(L)₂]·2CH₂Cl₂. The aroylbis(thioureas) are doubly deprotonated and the resulting anions {L^2–} bond to metal ions through (S,O)-chelating moieties. The copper atoms adopt a virtually cis-square-planar environment. In the crystal, adjacent [Cu₂(L)₂]·2CH₂Cl₂ units are linked into polymeric chains along the a-axis direction by intermolecular coordinative Cu⋯S interactions. The co-crystallized solvent molecules play a vital role in the crystal packing. In particular, weak C—H_furan⋯Cl and C—H_ethyl⋯Cl contacts consolidate the three-dimensional supramolecular architecture.

Keywords: crystal structure; aroylbis(N,N-dialkylthioureas); Cu(II) complexes.

1. Chemical context

Benzoyl(N,N-dialkylthioureas) are versatile ligands forming stable complexes with a great number of transition-metal ions, in which the organic compounds mainly act as monoanionic and (S,O)-bidentate ligands (Fitzl et al., 1977 ; Knuuttila et al., 1982 ; Sieler et al., 1990 ; Bensch et al., 1995 ; Nguyen et al., 2007 ; Barnard et al., 2019 ; Pham et al., 2021 ). This coordination fashion also plays an important role in metal complexes of aroylbis(thioureas), such as homo-dinuclear complexes based on the bipodal iso-phthaloylbis(N,N-dialkylthioureas) (Koch et al., 2001 ; Rodenstein et al., 2008 ; Schwade et al., 2013 ; Schwade et al., 2020 ; Teixeira et al., 2020 ). The presence of potential donor atom(s) in the spacer between two aroylthiourea moieties, such as pyridine N or catechol O atoms, could enable the corresponding aroylbis(thioureas) to serve as building blocks for the construction of heteronuclear host–guest systems (Nguyen et al., 2016 ; Pham et al., 2017 , 2020 ; Le et al., 2019 ; Jesudas et al., 2020 ). However, it seems such aroylbis(thioureas) are not appropriate for the production of homonuclear systems. Indeed, all efforts to produce related homonuclear complexes, as in the case of iso-phthaloylbis(N,N-dialkylthioureas), have hitherto failed. Herein, we describe the synthesis and crystal structure of the first homonuclear complex derived from the novel 3,3,3′,3′-tetraethyl-1,1′-(furan-2,5-dicarbonyl)bis(thiourea) (H₂L), referred to as furan-2,5-dicarbonylbis(N,N-diethylthiourea), which possesses a potential furan O donor atom in the molecular backbone. The compound, [Cu₂(L)₂], potentially exhibits interesting magnetic and catalytic properties (Pham et al., 2019 ; Nath et al., 2020 ).

2. Structural commentary

The complex [Cu₂(L)₂] crystallizes as a solvated form in the centrosymmetric monoclinic space group P2₁/n with half of [Cu₂(L)₂]·2CH₂Cl₂ in the asymmetric unit. The molecular structure, including solvent molecules, is shown in Fig. 1. The complex consists of two Cu^II ions and two doubly deprotonated ligands {L}^2–, which bond to the metal ions through (S,O)-chelating aroylthiourea moieties. The Cu1—O bond lengths are Cu1—O10 = 1.9406 (15) Å and Cu1—O20 = 1.9431 (14) Å, while the Cu1—S10 and Cu1—S20 bond lengths are 2.2624 (6) and 2.2612 (6) Å, respectively. These bond distances fall in the same ranges for those observed in several copper(II) complexes with aroylmono(thioureas) (Wu et al., 2015 ; Selvakumaran et al., 2016 ; Binzet et al., 2018 ; Pham et al., 2021) and aroylbis(thioureas) (Rodenstein et al., 2008; Schwade et al., 2013; Teixeira et al., 2020). The metal⋯metal distance is 7.762 (3) Å and the midpoint between the two copper atoms is on the inversion center of the molecule. The two chelate planes Cu1/O10–S10 (r.m.s.d. = 0.075 Å) and Cu1/O20ⁱ–S10ⁱ (r.m.s.d. = 0.156 Å) form a dihedral angle of 15.32 (2)°. Thus, the four-coordinate Cu^II atoms adopt a flat isosceles trapezoid geometry due to the cis arrangement of the donor atoms. The atoms within the furan-2,5-dicarboxamide moieties and the copper atoms are nearly coplanar with a largest deviation of 0.298 (2) Å from the mean least-squares plane for the furan oxygen atoms. Two CH₂Cl₂ molecules are located on either side of the plane at a distance of 1.991 (5) Å from the plane to the solvent carbon atoms. One chlorine atom of the solvent molecule is disordered over two positions with occupancy factor of 0.6163 (9) for the atom labelled A. In addition, the solvent interacts with the complex through hydrogen bonds formed with the carbonyl oxygen atoms O10 (Table 1).

3. Supramolecular features

Each [Cu₂(L)₂]·2CH₂Cl₂ unit interacts with two adjacent ones by long bonding interactions between the Cu^II ions and S20 atoms of adjacent blocks (Fig. 2a). These bonds, with a distance of 2.9884 (6) Å, are considerably longer than the coordinative Cu—S bonds within the [Cu₂(L)₂] unit. Such interactions between the units results in polymeric chains along the a-axis direction (Fig. 2b).

Furthermore, intermolecular hydrogen bonds (Table 1) involving the solvent molecules and the C—H bonds of the furan rings and ethyl groups are responsible for aggregation of the polymeric chains (Fig. 3).

4. Database survey

The crystal structures of neither the ligand nor its metal complexes are found in the Cambridge Structure Database (CSD version 5.45, update of June 2024; Groom et al., 2016 ). A search of the CSD for dinuclear copper(II) complexes derived from aroylbis(thioureas) reveals only five hits involving isophthaloyl derivatives: DIZTEM and DIZTEM1 (Rodenstein et al., 2008), BEWKAR (Schwade et al., 2013), DOMNIE (Selvakumaran et al., 2014 ) and YUFNUL (Teixeira et al., 2020). Across the series of metrics for these structures, all values regarding the coordination of copper(II) ions and aroylthiourea moieties are in accordance with those reported herein.

5. Synthesis and crystallization

H₂L (38.5 mg, 0.1 mmol) was added into a solution of CuCl₂·2H₂O (17.1 mg, 0.1 mmol) in 1 mL of MeOH. The reaction mixture was stirred at 313 K for 30 min before adding the supporting base Et₃N (0.03 mL, 0.2 mmol). A brown precipitate deposited immediately. After stirring for additional 1 h at 313 K, the product was filtered off, washed with MeOH, and dried under reduced pressure. Single crystals suitable for X-ray analysis were obtained by slow evaporation of a solution of the complex in a mixture of CH₂Cl₂ and MeOH. Under ambient conditions, the crystals slowly turned to powder due to the evaporation of the co-crystalized solvent.

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.
