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 x 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

Organic Framework

The compound [Cd(4,4'-bpy)2(H2O)2](ClO4)2·(L)2 was obtained by the reaction of Cd(ClO4)2, bis(1-pyrazinylethylidene)hydrazine (L) and 4,4'-bipyridine in aqueous MeOH. Single-crystal X-ray diffraction has revealed its two-dimensional metal-organic framework. The 2-D layers superpose on each other, giving a channel structure. The square planar grids consist of two pairs of shared edges with Cd(II) ion and a 4,4'-bipyridine molecule each vertex and side, respectively. The square cavity has a dimension of 11.817 × 11.781 Å. Two guest molecules of bis(1-pyrazinylethylidene)hydrazine are clathrated in every hydrophobic host cavity, being further stabilized by π-π stacking and hydrogen bonding. The results suggest that the hydrazine molecules present in the network serve as structure-directing templates in the formation of crystal structures.
