| Abstract Scope |
Crystal structure of the microporous compound, Nickel-3-amino-isonicotinate (Ni-NH2-INA) was investigated using the Microdiffraction Facility of ChemMatCARS at the Advanced Photo Source (APS). The structure with solvent of crystallization, tetrahydrofuran (THF), was determined to be orthorhombic, space group Pnn2, a=12.089(3) Å, b=6.91331(2) Å, c=10.5056(3) Å, V=2878.01(4) Å3, Z=2, and Dc=1.532 gcm-1. The nickel sites are 6-fold coordinated, each nickel is bonded to four oxygens from two carboxylate groups, and to two N sites of the pyridine groups. The rigid 3D connected network depicts a pseudo-square shaped pore channel with disordered THF, and the Ni sites form the corners (anchors) of these pores. This material including the entrapped solvent can be described with a chemical formula C16H18N4NiO5. The CO2 sorption curves of evacuated Ni-NH2-INA show a type-I behavior. Further structure studies of Ni-NH2-INA using in situ X-ray technique as a function of pCO2 at APS were conducted and results will be discussed. |
