Dichlorido{(E)-2,4,6-trimethyl-N-[phenyl(2-pyridyl)methylidene]aniline-κ2 N,N′}palladium(II)
The title complex, [PdCl2(C21H20N2)], contains a PdII atom in a slightly distorted square-planar coordination environment defined by two N atoms from one 2,4,6-trimethyl-N-[phenyl(2-pyridyl)methylidene]aniline ligand and two Cl atoms, forming a five-membered ring (N—Pd—N—C—C)
Single Crystal to Single Crystal (SC-to-SC) Transformation from a Nonporous to Porous Metal-Organic Framework and Its Application Potential in Gas Adsorption and Suzuki Coupling Reaction through Postmodification
A new amino-functionalized strontium-carboxylate-based metal-organic framework (MOF) has been synthesized that undergoes single crystal to single crystal (SC-to-SC) transformation upon desolvation. Both structures have been characterized by single-crystal X-ray analysis. The desolvated structure shows an interesting 3D porous structure with pendent -NH2 groups inside the pore wall, whereas the solvated compound possesses a nonporous structure with DMF molecules on the metal centers. The amino group was postmodified through Schiff base condensation by pyridine-2-carboxaldehyde and palladium was anchored on that site. The modified framework has been utilized for the Suzuki cross-coupling reaction. The compound shows high activity towards the C-C cross-coupling reaction with good yields and turnover frequencies. Gas adsorption studies showed that the desolvated compound had permanent porosity and was microporous in nature with a BET surface area of 2052 m(2) g(-1). The material also possesses good CO2 (8 wt%) and H-2 (1.87 wt%) adsorption capabilities
