• A cadmium coordination polymer with kgd sheet structure has been synthesized and structurally characterized.
• Complex 1 exhibits photoluminescence with an emission maximum at 411 and 406 nm at 298 and 77 K, respectively.
• Complex 1 contains uncoordinated NO3− anions which can be exchanged by BF4− or PF6−.
A cadmium coordination polymer with ‘Kagomé dual’ (kgd) sheet structure, {[Cd(tipa)2]·2NO3·5DMF}n (1), has been synthesized by employing an elongated triangular rigid N-containing ligand tris(4-(1H-imidazol-yl)phenyl)amine (tipa) and structurally characterized by X-ray single-crystal diffraction. The Cd(II) ion is six coordinated with N atoms from tipa ligands, forming a CdN6 octahedron geometry. The tridentate tipa ligand connects the Cd(II) ions into a 2D sheet. Topologically, if the triangular tipa ligand and the Cd(II) ions are regarded as 3- and 6-connected nodes respectively, the overall 2D sheet can be simplified to a (3,6)-connected kgd net with a Schläfli symbol of (43)2(46·66·83). Moreover, the photoluminescence at 298 and 77 K and anion exchange properties of 1 were also discussed.
