Syntheses and magnetic properties of high-dimensional cucurbit[6]uril-based metal–organic rotaxane frameworks†
Abstract
Three new high-dimensional cucurbit[6]-based metal–organic rotaxane frameworks [Co2(PR43)(BDC)2Cl2]·4H2O (1), [Co2(PR43)(BTC)2]·6H2O (2) and [Co2(PR43)(BPT)2]·20H2O (3) were obtained via the hydrothermal synthesis method. Compound 1 comprised a two-dimensional layered structure, while compounds 2 and 3 exhibited three-dimensional pillared structures. All the compounds showed good thermal stabilities. Furthermore, the magnetic properties of compounds 1–3 were also investigated in detail.
