ABSTRACT
A novel zinc complex (ZnE) has been designed and
synthesized based on the derivative of 2-(2΄-hydroxyphenyl)-1-H-benzimidazole (HBI) and the neutral
nitrogen-containing ligand (phen). The crystal of the title complex crystallizes in
the monoclinic system, space group P21/n with a = 10.2631(2), b = 34.2166(6), c = 11.4103(3) Å, β = 96.771(2)°, Mr= 844.24, V = 3978.99(14) Å3, Z = 4, the final R = 0.0400
and wR = 0.1001 for 8107 observed reflections (I > 2σ(I)). In
the title complex,
the free protonated phenoxide moiety (4-OH)
is successfully retained to realize pseudo-intramolecular hydrogen bonds with
the coordinated O atom from the other ligand.
