Organic Framework

A novel CdIImetal–organic framework, [Cd(C3H2O4)(NH3)]n, was synthesized by liquid diffusion conducted in the presence of ammonia. The CdIIatom has seven-coordinate O6N pentagonal–bipyramidal geometry. Six CdIIcenters are joined by six malonate ligands to form anS6-symmetric [Cd6(malonate)6] metallomacrocycle, which is further extended through a side-on chelating malonate ligand to form a three-dimensional network. Topologically, each CdIIcenter is connected to four others to yield an infinite three-periodic four-coordinated SOD (sodalite) network with point symbol {42·64}. The overall network structure in the crystal is maintained and stabilized by the presence of N—H...O hydrogen bonds.

The results showed that 1 was a 1D chain structure to be joined together by hydrogen bonds to generate a 3D supramolecular structure. CO2 and N2 adsorption behavior of the material was studied. It is significative that 1 can selective sorption of CO2.

The reaction of silver(I) nitrate with the mono-substituted pyrazine carboxamide ligand,N-(pyridin-2-ylmethyl)pyrazine-2-carboxamide (L), led to the formation of the title compound with a metal–organic framework (MOF) structure, [Ag(C11H10N4O)(NO3)]n, poly[μ-nitrato-[μ-N-(pyridin-2-ylmethyl-κN)pyrazine-2-carboxamide-κN4]silver(I)]. The silver(I) atom is coordinated by a pyrazine N atom, a pyridine N atom, and two O atoms of two symmetry-related nitrate anions. It has a fourfold N2O2coordination sphere, which can be described as distorted trigonal–pyramidal. The ligands are bridged by the silver atoms forming–Ag–L–Ag–L–zigzag chains along thea-axis direction. The chains are arranged in pairs related by a twofold screw axis. They are linkedviathe nitrate anions, which bridge the silver(I) atoms in a μ2fashion, forming the MOF structure. Within the framework there are N—H...O and C—H...O hydrogen bonds present.

The title compound, [Cu(C11H9N4O)(CH3CO2)]·2H2O (CuL), is a hydrated copper acetate complex of the ligandN-[(pyridin-4-yl)methyl]pyrazine-2-carboxamide (HL). Complex CuLhas a metal–organic framework (MOF) structure with a 10 (3) network topology. The ligand coordinates in a bidentate and a bis-monodentate manner, bridging three equivalent CuIIatomsviathe pyridine N atom and the second pyrazine N atom. The CuIIatom has a fivefold coordination sphere, CuN4O, being coordinated to three N atoms of the ligand and the acetate O atom in the equatorial plane and to the second pyrazine atom in the apical position. This gives rise to a fairly regular square-pyramidal geometry. In the crystal, the water molecules are linked to each other and to the three-dimensional frameworkviaO—H...O hydrogen bonds. There are also a number of C—H...O hydrogen bonds present within the framework.
