A team of German and Dutch scientists synthesized a series of substances, which show bright luminescence under UV light.  “The compounds decompose upon contact with oxygen or moisture. Because of that, all chemicals must be thoroughly dried in specialized vacuum ovens and all... [mehr]

Li9GaP4, reveals a high superionic conductivity of 1.6 mS cm–1 and a low activation energy. Li9GaP4 is easily accessible via ball milling of the elements and subsequent annealing at quite moderate temperatures. Temperature-dependent single-crystal X-ray diffraction reveals that... [mehr]

In this review, examples of borderline cases at the transition from “locally delocalized electrons” to delocalized electronic systems are summarized, with a special focus on examples that occur as anions in solution and in extended solids.    Klein W., Schier A., Fässler T.F.... [mehr]

The unique three‐dimensional structure of spherical, homoatomic nine‐atom germanium clusters opens various possibilities for the spatial arrangement of functional groups. Ligands comprising lone pairs have recently been introduced in the cluster sphere, and we now report the... [mehr]

The lithium phosphidoaluminate Li9AlP4 represents a promising new compound with a high lithium ion mobility.This triggered the search for new members in the family of lithium phosphidotrielates, and the novel compounds Li3AlP2 and Li3GaP2, obtained directly from the elements via... [mehr]
