DOI: 10.1007/s10870-019-00797-2
Abstract: Two new M(II)–radical complexes [M(hfac)2(NITPhSCH3)2] (M = Co (1), Mn (2); NITPhSCH3 = 4′-thiomethylphenyl-4,4,5,5-tetramethyl-imidazoline-1-oxyl-3-oxide; and hfac = hexafluoroacetylacetonate) have been synthesized and characterized by X-ray diffraction analysis, element analyses, IR and UV–Visible spectroscopy. X-ray analysis reveals that the structures of both… read more here.

Exciton-Polaron Spectral Structures in Two-Dimensional Hybrid Lead-Halide Perovskites
Sign Up to like & getrecommendations! Published in 2018 at "Physical Review Materials"
DOI: 10.1103/physrevmaterials.2.064605
Abstract: Owing to both electronic and dielectric confinement effects, two-dimensional organic-inorganic hybrid perovskites sustain strongly bound excitons at room temperature. Here, we demonstrate that there are non-negligible contributions to the excitonic correlations that are specific to… read more here.

DOI: 10.1107/s2056989017006120
Abstract: The two orthophosphates BaMn2Fe(PO4)3 and SrMn2Fe(PO4)3 are isotypic and resemble an alluaudite-like structure. The chains characterizing the alluaudite structure are built up from edge-sharing [MnO6] and [FeO6] octahedra linked by PO4 tetrahedra. read more here.
