Source of material
The title compound was prepared by the following method: to the round bottom flask were added 3,3′-dichloro-5,5′-bi-1,2,4-triazine (0.46 g, 2 mmol) in anhydrous dioxane 15 mL and 2-tri(n-butylstannyl)furan (2.52 mL, 8.0 mmol) and Pd(PPh3)4 (0.23 g, 10 mol%). The reaction mixture was refluxed for 24 h. The solvent was evaporated and the precipitate was filtered. The filtrate was dissolved in ethyl acetate and washed in portions with brine. The organic layer was evaporated and purified by column chromatography using dichloromethane. Crystallisation from ethyl acetate/hexane gives a yellow solid as main product and 3-chloro-3′-(furan-2-yl)-5,5′-bi-1,2,4-triazine as side product. 0.46 g; Yield 79%, mp. 269–270 °C. IR (KBr) cm−1: 3145(CH3), 1531–1584, 1094 (C—O—C). 1H NMR (400 MHz, CDCl3): δ 9.69 (s, 1H, CH), 7.85 (d,J = 3.6 Hz, 1H, CH), 7.68 (d, J = 1.6 Hz, 1H, CH), 6.62 (dd, J1 = 1.6 Hz, J2 = 3,6 Hz, 1H, CH). 13C NMR (100 MHz, CDCl3): δ 155.99, 154.19, 153.11, 144.48, 142.81, 128.24, 120.00. Elemental analysis for C14H8N6O2 calcd.: C: 57.50; H: 2.70; N: 28.80. Found: C: 57.45; H: 2.68; N: 28.70. Crystals suitable for X-ray structure analysis were grown by slow evaporation of a chloroform solution.
Experimental details
All hydrogen atoms were identified in difference Fourier syntheses and treated as riding on their parent C atoms with C—H distances of 0.93 Å (aromatic) and Uiso(H) = 1.5Ueq(C) in the refinement procedure.
Discussion
Nitrogen-containing heterocycles are extensively used as bridging ligands in coordination and supramolecular chemistry. Heterocyclic compounds containing soft donor atoms are capable of separating two groups of elements. For example, it has been reported that ligands containing aromatic N atoms as donor atoms coordinate An(III) more strongly than Ln(III), due to a greater covalent character of the An(III)—N bond [1], [2], [3]. As a continuation of our structural study on 6,6′-bis(substituted)-5,5′-bi-1,2,4-triazines as potential N-heterocyclic ligands for the extraction of nuclear waste [4], we describe in this paper the crystal structure of 3,3′-di(furan-2-yl)-5,5′-bi-1,2,4-triazine.
The two 3-(furan-2-yl)-1,2,4-triazine parts of the title molecule are connected by the Csp2–Csp2 single bond of 1.488(3) Å. The two parts are related by a crystallographic center of symmetry and consequently they possess trans conformation. The furan and 1,2,4-triazine rings are planar to within 0.0033(18) and 0.0091(15) Å, respectively, and they are almost coplanar confirmed by the torsion angle N4—C3—C7—O8 of 179.51(12)°. The molecule is planar as a whole, which is characteristic for π-conjugated organic systems. The consequence of this conjugation is occurrence of strong intramolecular interaction N2⋯O8 with the distance between N2 and O8 atoms of 2.7600(19) Å significantly shorter than the sum of the van der Waals radii of nitrogen and oxygen (3.07 Å). Similar effect is observed e.g. in 2,2′-bi(3,4-ethylenedioxythiophene π-conjugated system [5]. There are no intermolecular hydrogen bonds in the crystal structure of the title compound. The molecular packing is determined by van der Waals interactions. Moreover, the pairs of the furan and 1,2,4-triazine rings belonging to the translation-related molecules in [010] direction show a centroid-to-centroid separation of 3.6825(12) Å and the angle between the overlapping planes of theses rings of 1.99(9)°. The π–π distances of 3.2241(7) and 3.2715(6) Å between furan ring at (x, y, z) and triazine ring at (x, −1 + y, z) and triazine ring at (x, y, z) and furan ring at (x, 1 + y, z), respectively, are close to van der Waals distance of about 3.4 Å for the overlapping π-aromatic ring systems.
