A series of transition metal and lanthanide complexes of 4 Prime -(4-carboxyphenyl)-2,2 Prime :6 Prime ,2 Double-Prime -terpyridine (HL, 1), namely [M(L){sub 2}]{center_dot}5H{sub 2}O (M=Ni, 2; Co, 3), [Zn(L){sub 2}]{sub n}{center_dot}0.5nH{sub 2}O (4) and [Ln(L){sub 3}]{sub n} (Ln=Nd, 5; Gd, 6; Er, 7) were hydrothermally synthesized and structurally characterized by single-crystal X-ray diffraction. Isomorphic compounds 2 and 3 are mononuclear molecules with two ligand chelating to the metal centers via tridentate terpyridyl, while compound 4 adopts 1D chain-like structure, in which five-coordinate zinc centers are surrounded by three ligands. Compounds 5-7 also display 1D chain-like structure, but the nine-coordinate lanthanide centers bonded by four ligands. Luminescent property indicates that compound 4 exhibits photoluminescence in the solid state at room temperature. - Graphical abstract: Six complexes of 4 Prime -(4-carboxyphenyl)-2,2 Prime :6 Prime ,2 Double-Prime -terpyridine were synthesized via assembly with transition metal and lanthanide ions, respectively. Among them, [Ni(L){sub 2}]{center_dot}5H{sub 2}O and [Co(L){sub 2}]{center_dot}5H{sub 2}O are monomers, while [Zn(L){sub 2}]{sub n}{center_dot}0.5nH{sub 2}O and [Ln(L){sub 3}]{sub n} display chain-like structures. Highlights: Black-Right-Pointing-Pointer Compounds of 4 Prime -(4-carboxyphenyl)-2,2 Prime :6 Prime ,2 Double-Prime -terpyridine were synthesized. Black-Right-Pointing-Pointer [Ni(L){sub 2}]{center_dot}5H{sub 2}O and [Co(L){sub 2}]{center_dot}5H{sub 2}O are monomers. Black-Right-Pointing-Pointer [Zn(L){sub 2}]{sub n}{center_dot}0.5nH{sub 2}O and [Ln(L){sub 3}]{sub n} display chain-like structures.
