A Family of Flexible Lanthanide Bipyridinedicarboxylate Metal–Organic Frameworks Showing Reversible Single-Crystal to Single-Crystal Transformations

A family of flexible lanthanide metal–organic frameworks, [Ln₂(bpydc)₃(H₂O)₃]·nDMF (denoted as SUMOF-6-Ln; Ln = Nd, Sm, Eu, Gd, Tb, Dy, Ho, and Er, H₂bpydc =2,2′-bipyridine-5,5′-dicarboxylic acid), was synthesized and characterized. SUMOF-6-Ln has a monoclinic space group <i>P</i>2₁<i>/c</i>. The three-dimensional framework contains chains of LnO_<i>n</i> (<i>n</i> = 7–8) polyhedra connected through the bpydc linkers forming 1D rhombic channels along the <i>c</i>-axis. SUMOF-6-Ln showed reversible breathing phenomenon upon desorption/adsorption of the solvent, with up to 27% changes of the unit cell dimensions and 23% changes of the unit cell volume. Single crystal X-ray diffraction (XRD) revealed that the desolvation and resolvation of SUMOF-6-Ln occurred via single-crystal to single-crystal transformations. The thermal behavior of SUMOF-6-Sm was also examined. SUMOF-6-Eu and SUMOF-6-Tb showed solid-state luminescent properties

3D Open-Framework Vanadoborate as a Highly Effective Heterogeneous Pre-catalyst for the Oxidation of Alkylbenzenes

Three three-dimensional (3D) open-framework vanadoborates, denoted as SUT-6-Zn, SUT-6-Mn, and SUT-6-Ni, were synthesized using diethylenetriamine as a template. SUT-6-Zn, SUT-6-Mn, and SUT-6-Ni are isostructural and built from (VO)₁₂O₆ B₁₈O₃₆(OH)₆ clusters bridged by ZnO₅, MnO₆, and NiO₆ polyhedra, respectively, to form the 3D frameworks. SUT-6 is the first vanadoborate with a 3D framework. The framework follows a semiregular <i><b>hxg</b></i> net topology with a 2-fold interpenetrated diamond-like channel system. The amount of template used in the synthesis played an important role in the dimensionality of the resulting vanadoborate structures. A small amount of diethylenetriamine led to the formation of this first 3D vanadoborate framework, while an increased amount of diethylenetriamine resulted in vanadoborates with zero-dimensional (0D) and one-dimensional (1D) structures. SUT-6-Zn was proved to be an efficient heterogeneous precatalyst for the oxidation of alkylbenzenes
