“…This is the preferred nitrogen atom for coordination as found for other metal complexes with benzimidazoles [28]. Information regarding the possible bonding modes of the picrate and benzimidazole rings may also be obtained from the IR spectra, such as 709, 744, 1272, 1363, 1434, 1487, and 1633 cm −1 [29]. This fact agrees with the result determined by X-ray diffraction.…”

A V-shaped ligand Bis(2-benzimidazolymethyl)amine (bba) and its nickel(II) picrate (pic) complex, with composition [Ni(bba)2](pic)2·3MeOH, have been synthesized and characterized on the basis of elemental analyses, molar conductivities, IR spectra, and UV/vis measurements. In the complex, the Ni(II) ion is six-coordinated with a N2O4 ligand set, resulting in a distorted octahedron coordination geometry. In addition, the DNA-binding properties of the Ni(II) complex have been investigated by electronic absorption, fluorescence, and viscosity measurements. The experimental results suggest that the nickel(II) complex binds to DNA by partial intercalation binding mode.

“…One bridging Br2 locates in the apical site. The bond distances between Pb1 and the bridging bromides range from 2.8744 (8) reported in the literature [19]. The Pb1-N1 bond distance is 2.623(6) Å , within the range of typical values (2.396-2.776 Å ) [20].…”

“…Among polyazaheteroaromatic compounds, tetrazole and its derivatives are very interesting ligands because they combine the possible bridging of pyrazoles (N1, N2-), imidazoles (N1, N3-), 1,2,3-triazoles (N1, N2, N3-), and 1,2,4-triazoles (N1, N2, N4-) with regard to the arrangement of their four nitrogen atoms (scheme 1). Benzimidazolyl normally forms coordination bonds through its amino nitrogen and the amino nitrogen serves as a potential hydrogen bond donor [7][8][9][10].…”

Four transition metal complexes, [Mn(Hbimtz) 2 (H 2 O) 2 (NCS) 2 ] (1), [Co(Hbimtz) 2 (H 2 O) 2 (NCS) 2 ] (2), [Pb(Hbimtz)Br 2 ] n (3), and {[Ag 2 (Hbimtz) 3 ]SO 4 Á 4H 2 O} n (4) (Hbimtz ¼ 1-[(1H-benzimidazol-2-yl)-methyl]-1,2,3,4-tetrazole), were synthesized and characterized by singlecrystal X-ray diffraction. The Mn(II) of 1 and Co(II) of 2 are six-coordinate with two nitrogen atoms from Hbimtz, two nitrogen atoms from thiocyanate and two water molecules. The geometry of Pb(II) in 3 is a distorted octahedron with two nitrogen atoms of two Hbimtz's and four Br À ions, including the weak bond between the Pb1 and N6 of Hbimtz. Complex 3 is assembled into a 1-D [PbBr 2 ] n inorganic chain by 2 -Br À and into a 2-D layer by weak interactions. The Ag(II) of 4 has two geometries, linear and tetrahedral. Hbimtz bridges the two kinds of Ag(II) into a 1-D helical chain. Fluorescence of 3 and 4 were also investigated.

A novel complex of cadmium (II) picrate (pic) with V-shaped ligand bis(N-allylbenzimidazol-2-ylmethyl)benzylamine (babb), with composition [Cd(babb)2](pic)2, was synthesized and characterized by elemental analyses and electrical conductivity, IR, and UV/visible spectra. The crystal structure of the complex has been determined by the single-crystal X-ray diffraction. In the complex, the coordination sphere around Cd (II) is distorted octahedral, six nitrogen atoms involved in coordination afforded by two tridentate ligand babb. Moreover, The DNA-binding properties of the ligand babb and Cd (II) complex were investigated by spectrophotometric methods and viscosity measurements, and the results suggest that they bind to DNA via an intercalation binding mode, and the Cd (II) complex shows higher affinity than the ligand.
