Abstract
Two isostructural transition metal complexes based on the 4,4'-{[2,2'-(ethane-1,2-bicarboxymethyl)] amino-bis (acetyl)} dibenzoic acid (H4L) were synthesized under hydrothermal conditions, namely, [M(H2L)(H2O)]·3H2O (M=Ni, 1 ; Co, 2). The two compounds were structurally characterized by infrared spectra, thermogravimetric analysis and single crystal X-ray diffractions. Compounds 1-2 are mononuclear units and further extended to generate the two dimensional structures by hydrogen-bonds and π-π interactions. Compounds 1 exhibit the high thermal stability.
