The lanthanide lead oxide nitrates LnPbO2NO3 with Ln = La, Pr, Nd, and Sm were synthesised by solid state reactions of the nitrates in air and subsequent reactions in sealed silica tubes under in situ generated NOx atmosphere. The crystal structure of LaPbO2NO3 was refined isotypically with BiPbO2NO3 in the tetragonal space group I4/mmm by means of Rietveld powder XRD. According to this refinement, an orientational disorder is present for the NO3− ions. The homologous LnPbO2NO3 compounds were indexed isotypically for Ln = Pr, Nd, and Sm, and their lattice parameters were refined. The structures contain [LnPbO2]+ layers, alternating with single [NO3]− layers. Thermal analyses (DTA/TG) were performed for LnPbO2NO3 compounds and magnetic measurements for NdPbO2NO3. The employment of LaPbO2NO3 as a precursor for oxide materials, or as an NOx storage material is considered.

Formation of CO<sub>3</sub><sup>2-</sup> and HCO<sub>3</sub><sup>-</sup> species without participation of the framework oxygen atoms upon chemisorption of CO<sub>2</sub> in zeolite |Na<sub>12</sub>|-A is revealed. The transfer of O and H atoms is very likely to have proceeded via the involvement of residual H<sub>2</sub>O or acid groups. A combined study by solid-state <sup>13</sup>C MAS NMR, quantum chemical calculations, and <i>in situ</i> IR spectroscopy showed that the chemisorption mainly occurred by the formation of HCO<sub>3</sub><sup>-</sup>. However, at a low surface coverage of physisorbed and acidic CO<sub>2</sub>, a significant fraction of the HCO<sub>3</sub><sup>-</sup> was deprotonated and transformed into CO<sub>3</sub><sup>2-</sup>. We expect that similar chemisorption of CO<sub>2</sub> would occur for low-silica zeolites and other basic silicates of interest for the capture of CO<sub>2</sub> from gas mixtures.
