Issue Date: | 2026 | Publisher: | De Gruyter | Abstract: | Two new metal-organic frameworks based on 2,2′-bipyridine-5,5′-dicarboxylate and lanthanide (Ln) metal ions were prepared under solvothermal conditions, using HCl as a modulator. JMS-8 and JMS-9 MOFs ([Ln(bpdc)3(dmf)(H2O)3·5dmf·1.5H2O]n) crystallised in a triclinic system with space group P1. The MOFs have rod SBUs that grow along the b-axis. The linkers connect the SBUs along the a-axis and c-axis giving a 3D network structure. The packing diagrams show large pores as viewed on the a-axis and smaller pores which can be viewed on the c-axis. The MOFs exhibit good thermal and chemical stability. Gas sorption studies revealed low surface areas and poor CO2 adsorption capacity. | URI: | https://cris.library.msu.ac.zw//handle/11408/7018 |
