The potential of silicon-based ligands in metal-organic frameworks

This paper presents a description of the synthetic procedures to two silicon-based ligands and to two new metal-organic frameworks (MOFs) derived from these ligands, as well as the results of magnetic measurements on the MOFs. It was found that the new Mn(II) and Co(II) MOFs behave as paramagnets at low temperatures, and one of the compounds (3) experiences first order transition due to a (possible) spin crossover phenomenon.
