Three new complexes: [M(L)(H2O)] [M = Zn (1), Co (2), Ni (3); H2L = 5-(pyridin-2-ylmethyl)aminoisophthalic acid] were synthesized under hydrothermal conditions at 180 °C and were characterized by elemental analysis, FT-IR spectroscopy, single-crystal X-ray diffraction, and thermogravimetric analysis (TGA). The results of X-ray diffraction analysis reveal that complexes 1-3 are isostructural and crystallize in the monoclinic system with space group P21/c. Each of the complexes displays a (3,3′)-connected two-dimensional (2D) wave-like network with (4,8 2) topology, within which five-membered uncoplanar N,N-chelated metallacycles are shaped. Delicate N-H...O and O-H...O hydrogen bonding interactions exist in complexes 1-3. Adjacent 2D layers are linked by intermolecular interactions, resulting in the construction of extended metal-organic frameworks (MOFs) in complexes 1 and 2. Copyright
