چکیده
A metal-organic framework [Cd(dppip)]n (1) based on 5-(diphenylphosphino)isophthalic acid (H2dppip) has been synthesized hydrothermally and characterized by IR spectroscopy, elemental analysis, and X-ray crystallography. [Cd(dppip)]n shows a sheet structure owing to carboxylate bridging with windows with dimensions 10.692× 9.325 Å2. The layers are further connected through P–Cd interactions to give a three-dimensional supramolecular network. The thermal analysis (DTA) of complex 1 exhibited an exceptionally high thermal stability (m. p. 452.8 ◦C). The compound shows fluorescence at ca. 418 nm upon excitation at 314 nm.
