Abstract Two new silver(I) complexes, formulated as [Ag 2 (L 1 ) ](picrate) ( ), {[Ag (terephthalate)](C H 5 OH) 3 (H O)} n = 1,3‐bis(2‐benzimidazyl)benzene, L 1,3‐bis(1‐methylbenzimidazol‐2‐yl)‐2‐thiapropane), were synthesized and characterized by X‐ray crystallography, elemental analysis, infrared, UV–Vis spectroscopy. The crystal analysis results showed that the complexes exhibited different structures: binuclear for one‐dimensional polymeric . Their Ag(I) centers displayed coordination...
Abstract A mononuclear Mn(II) complex [Mn( p -MOPhH 2 IDC) (H O) ]·2(DMF), was synthesized by the reaction of 3 IDC (2-(4-methoxyphenyl)-1 H -imidazole-4,5-dicarboxylic acid) and Mn(CH COO) ·4H O under solvothermal conditions characterized single-crystal X-ray diffraction, elemental analysis, IR UV–vis spectroscopy. The structure analysis revealed that manganese(II) center has a six-coordinated octahedral coordination geometry. performance complex-doped carbon paste electrode (Mn-CPE) in...
Two new silver(I) complexes, formulated as [Ag 2 L 1 (isophthalate)]·(C H 5 OH) (1) , (isophthalate)] (2) (L = 1,3‐bis[(N‐methyl‐benzimidazole)methylene]‐2‐aniline, 1,3‐bis[(N‐ethyl‐benzimidazole)methylene]‐2‐aniline), were synthesized by volatilization method and characterized X‐ray crystallography, elemental analysis, IR UV/Vis spectroscopy.

Abstract A highly sensitive fluorescence “turn‐on” 1,8‐naphthalimide Schiff base probe: N ‐allyl‐4‐(ethylenediamine‐salicylidene)‐1,8‐naphthalimide (HL) for Hg 2+ was designed, synthesized and characterized. In addition, the sensing behavior of HL towards various transition metal ions has been investigated in solution (DMF/Tris–HCl buffer, 1:1, vol/vol, pH = 7.2). The exhibited high selectivity over other with obvious enhancement. Moreover, intensity showed good linearity a correlation...
Two new Zn(II)-Pr(III) heteronuclear clusters were synthesized by interfacial diffusion, [ZnPr(L)(NO3)2(OAc)(CH3OH)]·CH3CN (1) and [Zn4Pr2L4(terephthalate)2]·(NO3)2 (2) (H2L = bis(3-methoxysalicylaldehyde-3-oxopene-1,5-diamine). They have been characterized elemental analysis, UV-Vis IR spectroscopy, single-crystal X-ray diffraction. Structural analysis revealed that 1 has a heterodinuclear structure, with Zn(II) in the inner cavity generated deprotonated ligands L2- Pr(III) larger outer...
A new Ag(I) coordination polymer, [Ag2(BBO)]n, H2BBO = 1,3-bis(benzimidazol-2-yl)-2-oxopropane, was synthesized by diffusion method and characterized. The structural analysis showed that the polymer has a 2D layered structure, each polymerization unit is composed of two BBO ligands four ions, which form types structures (border silvers center silvers). hydrogen evolution reaction (HER) performance composite electrode CE-Ag formed mixing carbon paste investigated linear scanning voltammetry...
