Two novel organic-inorganic hybrid compounds with straight and zigzag chain alignments of Cu(II) centers: Synthesis, crystal structure, spectroscopy, thermal analysis and magnetism

Abstract Two hybrid salts, viz. bis(guanidinium) bis(oxalato)cuprate(II) (1) and bis(2-aminopyridinium) bis(oxalato)cuprate(II) trihydrate (2) have been synthesized and characterized by elemental and thermal analyses, IR spectroscopy, single-crystal X-ray diffraction and SQUID magnetometry. Compounds 1 and 2 crystallize in the monoclinic P21/c and triclinic P1ˉ space groups, respectively. In both structures, the four-coordinated Cu(II) ion in [Cu(C2O4)2]2- unit weakly interacts with two axial O-atoms of neighboring units to build a prolate CuO6 octahedron, with regular axial Cu-O bonds of 2.825 ? in 1, whereas in 2 two different Cu-O bonds (2.814 ? and 2.701 ?) are found. In 1, stacking of [Cu(C2O4)2]2- units across internal symmetry-related O-atoms results in equidistantly spaced monomers, thus forming straight Cu(II) chains with regular spacing of Cu?Cu = 3.582 ?. By contrast, in 2, stacking of the [Cu(C2O4)2]2- entities occurs via external symmetry-related O-atoms, yielding zigzag Cu(II) chains with shorter intra-dimer spacing of [Cu?Cu]intra = 3.430 ? and longer inter-dimer spacing of [Cu?Cu]inter = 4.961 ?. The anhydrated compound 1 is stable up to 250 °C, whereas the hydrated compound 2 shows a significant weight loss of solvent water molecules at about 70°C, followed by the decomposition of the network. The magnetic measurements in the 2-300 K temperature range revealed weak antiferromagnetic coupling in the two hybrid salts.

Analysis of the CO2 and NH3 reaction in an aqueous solution by 2D IR COS: Formation of bicarbonate and carbamate

The two-dimensional (2D) infrared correlation spectra obtained from the reaction time- and concentrationdependent IR spectra elucidates the reaction of CO2 and NH3 in an aqueous solution for CO2 absorption. In the synchron
