Crystal structure of bis[μ-1-[(2-ethyl-1H-imidazol-1-yl)methyl]-1H-benzotriazole-κ2N:N′]bis[dibromido]dimercury(II), C24H26Br4Hg2N10

Abstract

C 24 H 26 Br4Hg 2 N 10 , triclinic, P (no. 2), a = 7.587(1) Å, b = 9.801(1) Å, c = 11.037(2) Å, α = 78.81(1)°, β = 86.41(1)°, γ = 75.97(1)°, V = 781.0 CCDC no.: 1267/4124 Source of materialThe ligand 1-[(2-ethyl-1H-imidazol-1-yl)methyl]-1H-benzotriazole (0.04 mmol, 0.0096 g) in methanol (6 mL) was added dropwise to a methanol solution (6 mL) of HgBr 2 (0.04 mmol, 0.0144 g) in methanol. The resulting solution was allowed to stand at room temperature. After three weeks colourless crystals were obtained. Experimental detailsH atoms were generated geometrically and re ned as riding atoms with C-H = 0.93 Å and U iso (H) = 1.2 times Ueq(C) for aromatic H atoms, with C-H = 0.97 Å and U iso (H) = 1.2 times, Ueq(C) for methylene H atoms, and with C-H = 0.96 Å and U iso (H) = 1.5 times Ueq(C) for methyl H atoms. The measured crystal was a non-merohedral twin (twin law).

Crystal structure of dibromido-bis[μ-1-[(2-methyl-1H-benzoimidazol-1-yl)methyl]-1H-benzotriazole-κN]mercury(II), C30H26Br2HgN10

“…Many symmetric imidazole and benzotriazole ligands have been applied [3,4]. However, studies involving asymmetric imidazole and benzotriazole ligands are rather rare [5,6]. …”

Structure of the mercury(II) mixed-halide (Br/Cl) complex of 2,2′-(5-tert-butyl-1,3-phenylene)bis(1-pentyl-1H-benzo[d]imidazole)

“…A survey of the structural investigations of mercury halide complexes with benzimidazole derivatives has shown that they come in two main types; polymeric, bridging either through the halide (Zhang et al, 2015;Li et al, 2007;Shen et al, 2005) or through alternative N atoms from the benzimidazole moieties (Xiao et al, , 2011Huang et al, 2006;Li et al, 2007Li et al, , 2012aDey et al, 2013;Du et al, 2011;Chen et al, 2013;Su et al, 2003;Xu et al, 2011), or discrete molecules, i.e. nonpolymeric (Xiao et al, 2011;Wu et al, 2009;Zhao et al ., 1998;Manjunatha et al, 2011;Wang et al, 2007Wang et al, , 2009Wang et al, , 2012Wang et al, , 2015Chen et al, 2014;Su et al, 2003;Quiroz-Castro et al, 2000;Yang & Luo, 2012;He et al, 2012;Bouchouit et al, 2015).…”
