Three new complexes were synthesized using hydrothermal method with different ligand combinations, resulting in structures with different properties. The crystal structures and intermolecular interactions were studied using single-crystal X-ray diffraction and Hirshfeld surface analysis. Additionally, the photoluminescence properties of one complex and the magnetic and electrochemical properties of another complex were investigated.
Three new complexes synthesized by hydrothermal method with 4-(3-Carboxy-phenoxy)-phthalic acid (H3L1) and 2-(4-Carboxy-benzyl)-terephthalic acid (H3L2) as main ligands, 1,10-phenanthroline (1,10-phen) 1,4-bis(1-imidazolyl)benzene(dib) and 1,4-di(pyridin-4-yl)benzene (4,4'-bipb) as auxiliary ligands: [Cd-3(L-1)(2)(1,10-phen) (2)center dot H2O](n) (1), [Co(HL2)(dib)(H2O)(2)](n) (2), [Co(HL2)(bipb)](n) (3). Single-crystal X-ray diffraction shows that 1 belongs to the monoclinic system and the P-1 space group, 2 belongs to the monoclinic system and the P-1 space group, 3 belongs to the triclinic system and the P21/n space group. Complexes 1-3 are 1-D chain, 2-D network and 3-D structures, respectively. Moreover, Hirshfeld surface analysis analyzed the intermolecular interaction and surface electron distribution of 1-3. The photoluminescence properties of complex 1 and magnetic, electrochemical properties of complex 3 were studied.
