Two 2-substituted 8-hydroxyquinoline ligands (HL1 and HL2) containing a cyano group were synthesized and characterized by ESI-MS, NMR spectroscopy and elemental analysis (EA). Solvothermal reactions of the two ligands with ZnX2 and CdX2 (X−: NO3− and OAc−) salts afforded three luminescent complexes, i.e., monomeric Zn(II) complex [Zn(L1)2] (1), trimeric Zn(II) complex [Zn3(L2)6] (2) and tetrameric Cd(II) complex [Cd4(L2)8] (3). These three complexes were characterized by single crystal X-ray diffractions, powder X-ray diffractions (PXRD), thermogravimetry analyses (TGA) and EA, illustrating a lamellar structure facilitated by noncovalent interactions such as aromatic π⋯π stacking and C–H⋯N H-bonds. Further investigations by UV–Vis, photoluminescence (PL) and fluorescence lifetime reveal tunable luminescence from yellow to red among 1–3 in the solid state.
