Abstract
A new heterometallic coordination polymer, namely [Cd2Ca2(PBDC)(H2O)2(e-urea)(DMF)]n·2n(DMF) (1 H2PBDC = terephthalic acid, DMF = N,N-dimethylformamide, e-urea = ethyleneurea) has been synthesized by combining the PBDC ligand with Cd(II) and Ca(II) salts under mixed solvothermal conditions. Single-crystal X-ray diffraction analysis reveals that 1 is an extended three-dimensional framework containing two distinct inorganic Cd–O–Ca chains, and can be simplified into a 4-connected topological network based on three unequivalent nodes. Luminescent study reveals that 1 exhibits strong, ligand-centred luminescence in the solid-state at room temperature.
