Diaquabis{2-[(5-méthylpyrazol-3-yl)méthyl]benzimidazole}nickel(II) dichloride dihydrate

Abstract: In the structure of the title compound, [Ni(C12H12N4)2(H2O)2]Cl2·2H2O, the Ni atom is linked to four N atoms and two water molecules in a distorted octahedral coordination geometry. The coordinated water molecules are engaged in hydrogen bonds with two other water molecules.

“…Continuing our research in this field (Chkirate et al, 2001;Sbai et al, 2002), we synthesized a zinc chloride complex having 2-[(5-methylpyrazol-3-yl)methyl]benzimidazole, obtained by the action of hydrazine on 4-acetonylidene-1,5-benzodiazepin-2-one (Essassi et al, 1987), as the main ligand. The asymmetric unit of the title compound consists of two independent molecules with modest but distinct differences in their conformations (Fig.…”
