TWO COMPLEXES ASSEMBLED FROM BIS(4-(1H-IMIDAZOL-1-YL)PHENYL)METHANONE AND BENZOIC ACID: SYNTHESES AND STRUCTURAL CHARACTERIZATION

Two complexes [Mn(H2O)4(L1)2](bz)2 (1) and {[Zn(L1)(bz)2]}n (2) (L1 = bis(4-(1H-imidazol-1-yl)phenyl) methanone, Hbz = benzoic acid) are synthesized under solvothermal conditions. They are characterized by IR, elemental, and single crystal X-ray diffraction analyses. The single crystal X-ray diffraction analysis shows that Mn1 in 1 has a distorted octahedral geometry with four O atoms from H2O and two N atoms from two L1 ligands, while Zn1 in 2 is four coordinated by two O atoms from two bz2– ligands and two N atoms from two L1 ligands, forming 1D helix chains along the a axis.
