We studied the thermo- and photo-induced phase transition between low spin (LS) and high spin (HS) states of the 2x2 grid-like iron complex: Fe4L44·C2H3N (FE4), L=4-methyl-3,5-Bis{6(2,2′-dipyridyl)}pyrazole in solid state, by using X-ray diffraction techniques. The structural analysis of the coordination geometry of the two crystallographically independent metal atoms at different...
Growing concern over resource availability and toxicity are leading to a paradigm shift towards truly sustainable materials for photovoltaics. Zn-group IV-nitrides are one potential class of materials fulfilling these criteria, which adopt a wurtzite-type derived structure. The ternary nitrides were postulated to allow a unique bandgap tuning mechanism through cation disorder$^{[1]}$ in...
The class of transition metal phosphates (TMPs) shows a wide range of chemical compositions, variations of valence states and respective crystal structures. Among TMPs, $VO(P_2O_7)$ and $LiFePO_4$ are of special interest as the only commercially used heterogeneous catalyst for the selective oxidation of butane to maleic anhydride [1] and cathode material in rechargeable batteries [2]. Due to...
The “fluoride route”, synthesis in the presence of fluoride anions, has been established as a versatile strategy for the synthesis of all-silica zeolites. Experimental investigations of as-synthesised zeolites using diffraction and NMR methods have shown that the fluoride anions are often located in small cages and bonded to one Si atom at a cage corner, with dynamic or static disorder...
Doping is a well-known method for improving gas sensing responses by metal oxide based functional materials.[1] And the plausible explanations provided in justification of using a specific dopant have been changes in material crystallinity, particle size, morphology and so on; but these ideas alone aren’t able to clearly highlight the fundamental changes and intricacies of a system that...
Heteroanionic hydrides are an emerging class of compounds with representatives showing hydride ion conductivity [1] or catalytic activity [2]. Their properties are fundamentally linked to their anionic substructure; for example, might a difference between ordered and disordered anions change their behavior from a conducting to an isolating behavior [3].
From the solid-state reaction of...
