“…This is a mononuclear compound due to the monodentate coordination mode of pyridinyl-benzimidazole molecules via a nitrogen of the pyridine ring. The more numerous group of zinc and pyridinyl-benzimidazole compounds also contains organic aromatic co-ligands with two or three carboxylate groups [ 62 , 63 , 64 , 65 , 66 , 67 , 68 , 69 , 70 ]. Such co-ligands form double or triple bridges, and depending on the coordination mode of pyridinyl-benzimidazole (monodentate or bidentate bridging as described above, or tridentate bridging after deprotonation of imidazole nitrogen) the one-, two- or three-dimensional polymeric networks are propagated.…”

Developing new, smart drugs with the anticancer activity is crucial, especially for cancers, which cause the highest mortality in humans. In this paper we describe a series of coordination compounds with the element of health, zinc, and bioactive ligands, benzimidazole derivatives. By way of synthesis we have obtained four compounds named C1, C2, C4 and C4. Analytical analyses (elemental analysis (EA), flame atomic absorption spectrometry (FAAS)), spectroscopic (Fourier transform infrared spectroscopy (FT-IR), mass spectrometry (MS)) and thermogravimetric (TG) methods and the definition of crystal structures were used to explore the nature of bonding and to elucidate the chemical structures. The collected analytical data allowed the determination of the stoichiometry in coordination compounds, thermal stability, crystal structure and way of bonding. The cytotoxicity effect of the new compounds as a potential antitumor agent on the glioblastoma (T98G), neuroblastoma (SK-N-AS) and lung adenocarcinoma (A549) cell lines and human normal skin fibroblasts (CCD-1059Sk) was also determined. Cell viability was determined by the MTT assay. The results obtained confirmed that conversion of ligands into the respective metal complexes significantly improved their anticancer properties. The complexes were screened for antibacterial and antifungal activities. The ADME technique was used to determine the physicochemical and biological properties.

Two cadmium complexes, {[Cd(a-ptt)(ptt)]-H2O¡,, (1) and [Cd(a-Hmtt)2(SO4)H2O]-CH3OH (2), have been prepared based on 4-amino-3-(4-pyridine)-5-mercapto-1,2,4-triazole (a-Hptt) and 4-amino-3-methyl-5-mercapto-1,2,4-triazole (a-Hmtt), respectively. In 1, amino-triazole ligand aHptt can partly be deaminated and transformed into 3-(4-pyridine)-5-mercapto-triazole (Hptt) under hydrothermal conditions. X-ray diffraction analysis reveals that I exhibits an unusual 2-D lampshade-type layer structure in which the amino ligand a-ptt and the deamination ligand ptt display eATo-tridentate bridging and bidentate bridging, respectively. Complex 2 is mononuelear and further assembled into a 3-D supramolecular architecture via non-covalent interactions. Complexes 1 and 2 were characterized by elemental analyses, IR, and thermogravimetric analyses. Furthermore, solidstate luminescent properties of 1 and 2 have also been investigated.

“…Free bim, pbim, and 2,2 0 -bipy display fluorescent emission bands at ca. 391, 386 and 530 nm, respectively [46][47][48]. The blue shifts of the emission bands that occur in 1, 2 and 3 are probably due to the cooperative effects of intraligand emission and ligand-to-metal charge transfer [49][50][51][52].…”

Three new metal coordination polymers, [Zn(oba)(bim)] n (1), [Zn(oba)(2,2 0 -bipy)] n (2) and [Zn(oba)(pbim)] n (3) [H 2 oba = 2-(4-carboxyphenoxy)benzoic acid, bim = benzimidazole,2,2 0 -bipy = 2,2 0 -bipyridine and pbim = 2-(4-Pyridyl)benzimidazole], were synthesized and structurally characterized by elemental analysis, IR and X-ray diffraction. Compound 1 is a two-dimensional supramolecular framework, which is connected by onedimensional chains through hydrogen bonding interactions. In compound 2, an alternate arrangement of the right-and left-handed helical chains through interchained p-p stacking interactions, formed a two-dimensional supramolecular framework. Compound 3 exhibited a 2D ? 3D interdigital architecture with side arms. In compounds 1, 2 and 3, the oba 2-ligands act as bridging ligands exhibiting three coordination modes to link metal ions; i.e., bis-monodentate, bidentate chelating and monodentate modes. The luminescent properties of 1, 2 and 3, were also investigated.
