In the title cadmium metal–organic framework complex, [Cd(C8H3NO6)(C24H16N2)]nor [Cd(NIPH)(dpphen)] (NIPH is nitroisophthalate and dpphen is 4,7-diphenyl-1,10-phenanthroline), the unique CdIIcation in a general position is coordinated by four carboxy O atoms from three symmetry-related NIPH anions and two N atoms from a dpphen ligand. The CdIIcations are bridged by pairs of NIPH anions to generate a dinuclear molecular building block, [Cd2N4(CO2R)4], with a Cd...Cd separation of 4.0936 (10) Å. Each such building block is connected to four adjacent dinuclear building blocks by NIPH anions, resulting in a two-dimensional layer framework in thebcplane. The dpphen ligands occupy the space between these layers and are linked by π–π interactions, with a separation of 3.4541 (6) Å between the central aromatic rings of inversion-related dpphen ligands. The thermogravimetric and photoluminescent properties of the complex have also been investigated.

Synthesis and Structure of a Clathrated Two-Dimensional Metal-Organic Framework: [Cd(4,4'-bpy)2(H2O)2](ClO4)2·(L)2·H2O (L = Bis(1-pyrazinylethylidene)hydrazine)

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.
