[Display omitted] •• Three new transition metal complexes ([Cd3(L1)2(1,10-phen)2·H2O]n (1), [Co(HL2)(dib)(H2O)2]n (2), [Co(HL2)(bipb)]n (3).) were synthesized.•• Complexes 1–3 are 1-D chains, 2-D network and 3-D structures, respectively.•• The luminescent properties of 1 have been explored and compared with that of the ligand.•• TGA,PXRD and Hirshfeld surface analysis of complexes (1–3) were studied.•• Magnetic properties and Electrochemical properties analyses for 3 were performed. 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: [Cd3(L1)2(1,10-phen)2·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.
