Source of materials

Imidazole (2 mmol), Zn(OAc)2 (0.25 mmol), V2O5 (0.3 mmol) and Et4NOH (0.3 mmol) were successively added to 10 mL water in a 25 mL flask, the mixture was ground together for 24 h. After the reaction was finished, the mixture was filtered and the filtrate was slowly evaporated at room temperature. The orange crystals were obtained, yield: 47%.

Experimental details

In the title compound, all non-hydrogen atoms were refined anisotropically. All hydrogen atomic positions were taken from a difference Fourier map. They were refined with variable isotropic displacement parameters. Their U iso values were set to 1.2U eq (C, N of imidazole ring) of the parent atoms, respectively. All the H atoms were refined as riding on their parent atom.

Comment

At present, transition metal zinc complexes have gained widespread attention in many fields due to their excellent thermodynamic stability, abundance, low-cost and non-toxic nature [3], [4], [5], [6]. Various ligands are used to synthesize zinc complexes with varying coordination numbers and geometries [7], [8], [9]. Particularly, the research and development of imidazole derivatives have continuously expanded in the last decades [10], [11], [12]. For instance, the related study reported the synthesis of a series of polyoxometalate complexes with imidazole derivatives as organic ligands and further investigated their electrocatalytic and photocatalytic activities [10]. However, there are only few reports available involving the study of imidazole-zinc polyoxovandates [13].

Single crystal X-ray diffraction analysis shows that the title compound contains one tetra-imidazole-zinc cation, and two crystallographically distinct V atoms. In the crystal structure, the Zn(II) atom is coordinated by four nitrogen atoms from four imidazole ligands, and the bond lengths of Zn–N are 1.974(3) Å, 1.982(3) Å, 2.013(3) Å and 2.016(3) Å, respectively. Additionally, the bond angles of N(5)–Zn(1)–N(1), N(5)–Zn(1)–N(7), N(1)–Zn(1)–N(7), N(5)–Zn(1)–N(3), N(1)–Zn(1)–N(3) and N(7)–Zn(1)–N(3) are 118.25(12)°, 110.71(13)°, 104.02(12)°, 106.24(13)°, 110.23(13)° and 106.94(13)°, respectively, which confirmed that the Zn center forms a tetrahedral coordination geometry. Clearly, the bond lengths and angles are normal and correspond to those discussed in Zn(C18H37-im)2Cl2 (im = imidazole) [14] and Zn(sac)2(im)2 (sac = saccharinate anion) [15]. It can be speculated that the tetrahedral Zn complex exhibits weak intermolecular core interactions due to steric effects of imidazole ligands. The bond lengths of V–O range from 1.569(4) Å to 1.848(5) Å and the O–V–O angles range from 92.1(3)° to 127.2(3)°, which are consistent with previously reported vanadates [16]. The V(1)O4 and V(2)O4 tetrahedra and their crystallographic partners formed the 1D chain by sharing the corners, alternately.

Additionally, the three dimensional supramolecular network of title compound was constructed by intermolecular weak C–H⋯O and N–H⋯O hydrogen-bonding interaction between the adjacent molecules.
