Source of material

Lithium imidazolate was prepared in analogy to a literature known synthesis [5]. In a 250 mL three necked round bottom flask, equipped with a condenser and fitted with a magnetic stirring bar, imidazole (5.00 g, 73.4 mmol) was suspended in toluene (50 mL). Under vigorous stirring nBuLi in hexanes (30 mL, 2.5 mol L−1, 75.1 mmol) was slowly added. The resulting pale yellow suspension was stirred at room temperature for 19 h and subsequently refluxed for 24 h, while a colorless solid precipitated. The suspension was cooled to room temperature, filtered over a glass frit, washed with toluene (3 × 20 mL), and dried in vacuum to yield 5.24 g (70.8 mmol, 96% calculated for imidazole) lithium imidazolate. Crystals of the title compound, poly[(μ 3-imidazolato-κ 3 N:N:N′)(tetrahydrofuran- κ 1 O)lithium(I)], were obtained from a saturated THF solution within 24 h.

Experimental details

All H atoms were located on a difference Fourier map and refined without any restraints.

Comment

Lithium imidazolate is a valuable starting compound for the synthesis of various imidazole-based derivatives and materials. Examples include biologically active compounds [6], ligands for coordination chemistry [7], and Li-ion conducting materials, weakly coordinating anions (WCAs), as well as components of electrolytes [5, 811]. Recently, we described the functionalization of both N atoms in lithium imidazolate by tricyanoborane moieties. The corresponding 1,3-bis(tricyanoborane)imidazolate anion was used for the formation of three-dimensional coordination polymers and as precursor for a new type of a ditopic dianionic N-heterocyclic carbene (NHC) [12]. Molecular lithium imidazolate was studied by theoretical methods [13], [14], [15]. Furthermore, Li–N coordination in imidazolate species is an important motif in coordination chemistry, e.g. in covalent organic frameworks [16] and zeolitic imidazolate frameworks (ZIFs) [17], [18]. Surprisingly, no crystal structure analysis on lithium imidazolate has been published, to date.

Solvent-free lithium imidazolate was synthesized by deprotonation of imidazole in toluene. Recrystallization of lithium imidazolate from THF gave the title compound, poly[(μ 3-imidazolato-κ 3 N:N:N′)(tetrahydrofuran-κ 1 O)lithium(I)], as a two-dimensional coordination polymer.

The asymmetric unit of the title compound contains one imidazolate anion [C3N2H3], one lithium cation Li+, and one THF molecule. The lithium cation Li1 is tetrahedrally coordinated by the O atom of THF (d(Li1–O1) = 1.959(2) Å) and N atoms of three different imidazolate anions (N1, N3″, N3‴; see the Figure). The Li–N distances of the bridging N atom (d(Li1–N3″) = 2.088(2) Å and d(Li1–N3‴) = 2.167(2) Å) are significantly shorter compared to d(Li1–N1) = 2.019(2) Å of the terminal coordinated N atom. The Li–N coordination results in a two-dimensional coordination polymer. In contrast, for lithium-bis(DMSO) benzimidazolate a chain structure was described, in which the Li ion is coordinated by two DMSO molecules and two N atoms of different benzimidazolate ions [19].
