The novel hybrid compounds Pb 2 Cu(O 2 C–CH 2 –NH 2 ) 2 X 4 (X = Br, Cl) were prepared and characterized by single‐crystal X‐ray diffraction. TA analysis and DSC measurements show that the compounds are stable up to 200 °C. As in hybrid perovskites, their layered structures are based on metal(II) halide 2D frameworks, which are here covalently linked by trans ‐Cu(Gly) 2 flat SBUs. These rigid pillars are able to accommodate some of the void that exists in between the PbX 2 layers. However, the results from hydrogen absorption experiments that were conducted at 77 K indicate that the hybrids are not good candidates for absorption materials. (© Wiley‐VCH Verlag GmbH & Co.
