Three CdII complexes based on 2-(1H-imidazol-1-methyl)-1H-benzimidazole and homologous aliphatic dicarboxylates

Synthesis, crystal structure and bovine serum albumin–binding studies of a new Cd(II) complex incorporating 2,2′-(propane-1,3-diyl)bis(1H-imidazole-4,5-dicarboxylate)

“…The dihedral angles between the mean planes defined the imidazole ring N1/N2/C2/C3/C5 and the coordinated and uncoordinated carboxylate groups are 2.0(2)° and 1.57(17)°, respectively, while the dihedral angles between the mean planes defined the imidazole ring N3/N4/C9/C11/C12 and the coordinated and uncoordinated carboxylate groups are 9.4(2)° and 1.61(18)°, respectively. The Cd–N bond lengths are 2.2781(13) and 2.2902(12) Å, while the Cd–O bond distances are in the range of 2.2992(11)–2.6023(11) Å, all of which are in the normal range of those observed in the reported Cd(II) complexes {[Cd(glu)(imb)]·H 2 O} n [imb = 2-(1H-imidazolyl-1-methyl)-1H-benzimidazole, H 2 glu = glutaric acid, Cd–N = 2.236(2)–2.325(2) Å, Cd–O = 2.212(2)–2.644(2) Å] 24 and [Cd 2 (cbimdaH) 2 (H 2 O) 6 ] n ·(DMF) 3 n ·(H 2 O) 3 n [cbimdaH 3 = 1-(4-carboxybenzyl)-1H-imidazole-4,5-dicarboxylic acid, Cd–N = 2.263(3)–2.294(3) Å, Cd–O = 2.252(4)–2.673(3) Å]. 25…”

Three-Dimensional Zn(II) Complex Based on 2-[(1H-Imidazol-1-yl)Methyl]-6-Methyl-1H- Benzimidazole and Aliphatic Carboxylate

“…7 Succinic acid has no contribution to the fluorescence emission of complex 1; similar cases have been reported. 18 In contrast to free immb, complex 1 shows a slightly red-shifted emission band caused by the metalligand coordination interactions which influence the rigidity and asymmetry of the ligands and the coordination environment of the metal centres. 19,20 In the case of complex 1, the decrease in fluorescence intensity may be due to the vibrational quenching by the presence of lattice water molecules.…”

Nanostructured electrodes for high-power lithium ion batteries

“…This has permitted incorporation of high C-rates with impressive cycle life due to the enhanced stability of the composite anode [59,60]. With the advent of graphene, there has been an interest in SnO 2 -graphene composites with the hope that the high surface area and superior electrical conductivity of graphene could enhance the rate capability [61,62].…”
