A highly complex crystal structure of stoichiometric Mg()(BH) was solved from single crystal synchrotron X-ray diffraction and confirmed by neutron powder diffraction (NPD) on isotopically substituted Mg()(BD). We highlight the role of the amorphous Mg(BH) in the reactivity of the Mg(BH)- system and characterized a previously overlooked phase, Mg()(BH).

Metal dodecaborates (MBH) are a versatile class of materials used in polymer chemistry and cancer treatment and are promising candidates as electrolytes for solid-state batteries. However, a general and scalable approach has not yet been developed for producing high-purity BH derivatives. In this work, we report a simple, efficient, and environmentally benign solvothermal method to prepare diffraction and B NMR pure NaBH (85% yield) and KBH (84% yield).

The first mesoporous bimetallic Ti/Al metal-organic framework (MOF) containing amine functionalities on its linkers has been selectively obtained by converting the cheap commercially available (TiCl)AlCl into TiAlCl(THF) and reacting this complex with 2-aminoterephthalic acid in dimethylformamide (DMF) under soft solvothermal conditions. This compound is structurally related to the previously described NH-MIL-101(M) (M = Cr, Al, and Fe) MOFs. Thermal gravimetric analyses and powder X-ray diffraction (PXRD) measurements demonstrated that this highly air-sensitive Ti-containing MOF is structurally stable up to 200 °C.

The metal sites of MIL-100(Fe), MIL-100(Fe,Al), and MIL-100(Al) metal-organic frameworks (MOFs) were decorated with ethylenediamine (EN). Interestingly, the Al-containing MOFs presented hierarchized porosity, and their structural integrity was maintained upon functionalization. Solution and solid-state NMR confirmed the grafting efficiency in the case of MIL-100(Al) and the presence of a free amine group.

In this study we present the crystal structure, spectroscopic and thermal behavior, Hirshfeld surface analysis, and DFT calculations of a new organic-inorganic hybrid compound (CHN)[CoCl]. This compound crystallizes in the centrosymmetric space group P1¯. Single-crystal X-ray diffraction analysis indicates that structure consists of a succession of mixed layers formed by organic cations and inorganic anions parallel to the (001) plane and propagate according to the c-axis.
