Source of material

The mixture of Zn(NO3)2⋅6H2O (1 mmol, 297.5 mg), 1,1′-(biphenyl-4,4′-diyl)bis(1H-imidazol) (bibp) (1 mmol, 286.3 mg), 4-bromobenzoic acid (2 mmol, 402.0 mg), dimethylformamide (1 mL) and H2O (3 mL) were placed in a 10 mL Teflon-lined autoclave at 373 K for 72 h, then cooled to room temperature. Colourless block crystals were obtained.

Experimental details

The hydrogen atoms were positioned geometrically with C–H = 0.93 Å. Their Uiso values were set to be 1.2Ueq of the parent atoms.

Comment

As an imidazole derivative, 1,1′-(biphenyl-4,4′-diyl)bis (1H-imidazol) (bibp) is a good neutral N-donor organic ligand to construct coordination polymers because of its versatile coordination modes [3], [4], [5], [6], [7], [8], [9], [10], [11]. In order to expand this research area, the title compound based on bibp ligand and the auxiliary ligand 4-bromobenzoic acid (BBA) was synthesised and its crystal structure determined.

In the title compound, the fundamental unit contains one Zn(II) cation, one bibp ligand, and two 4-bromobenzoate ligands. The Zn(II) cation is four coordinated by two O atoms from two crystallographically independent 4-bromobenzoate ligands (Zn–O = 1.959(3)–1.967(3) Å), and two N atoms from two symmetry related bibp ligands (Zn–N = 1.996(3)–2.032(3) Å), forming a distorted tetrahedral geometry (see the figure). Geometric parameters are all in the expected ranges [12]. The bridging bibp ligands link adjacent Zn(II) cations to form a chain structure with the Zn–Zn distance of 17.797 Å along the b axis.
