| Abstract: | Four new coordination compounds, Cd(L1)2]n ( 1 ), Mn(L1)2]n ( 2 ), Zn(L1)(NA)] ( 3 ), and Pb(L1)2(H2O)] ( 4 ) were obtained on the basis of the in‐situ ligand reactions of quinoline‐2‐carbonitrile (QCN) and NaN3 under solvothermal conditions. 1 and 2 are 1D isostructural chains, where the central metal atoms are six‐coordinate by six nitrogen atoms in a distorted octahedron. The cycloaddition reaction of QCN and NaN3 in the presence of hydrated ZnCl2 occur with the aid of the ancillary ligand nicotinic acid (NA), where NA not only provides an acidic environment but also serves as an ancillary ligand. The extended structure of 3 is a 1D ladder‐like polymer. Compound 4 is a mononuclear Pb2+ compound. All the compounds were structurally characterized by X‐ray crystallography and their luminescent properties were investigated in detail. |
