Four new coordination polymers (CPs),{[Zn2 (L) 4]· 7H2O} n (1),{[Zn2 (L) 4]· 4H2O} n (2),{[Zn (L) 2]· 3/2H2O} n (3) and {[Cd (L) 2]· 3H2O} n (4)(HL= 4-benzoimidazol-1-yl-methyl benzoic acid) have been synthesized under hydrothermal conditions. All the complexes have been characterized by single crystal X-ray crystallography (XRD), IR spectroscopy, elemental analysis and thermogravimetry (TGA). Complexes 1–4 show similar 2D, non- ...
