“…The feature of chiral 61 chains of face--or edge--sharing polyhedra has been found previously, e.g., in the crystal structures of CsCuCl3 [36,37] or AuF3 [38]. dimensional structural features -chains of Be and B atoms -discussed above (see SI for more details).…”

LiBeB: A predicted phase with structural and electronic peculiarities

et al. 2012

Beginning an in--depth analysis of binaries and ternaries in the Li/Be/B system, we examine the static structures and electronic properties of LiBeB (i.e 1:1:1) over a range of pressures. This as yet unknown compound is predicted to possess a stable ground state at 1 atm and some higher pressures. As the pressure rises, LiBeB goes through a diverse series of structures, beginning with metallic structures which feature chains and layers of atoms, progressing to structures built on "colorings" of the Laves phases, and containing helical arrangements of boron atoms, on to high pressure phases that are ternary variants of a bcc lattice. The density of states (DOS) at the Fermi level consistently falls in a pseudogap (sometimes a real gap is predicted); LiBeB is unlikely to be a good metal or superconductor. The distribution of the DOS follows what electronegativity would predict -Li electrons are 2 transferred to B. Some curious features of the LiBeB structures emerge, these include near--icosahedral coordination, independent of atom type; in a range of pressures a resemblance of the total DOS to that of metallic Be; and also a Dirac surface.3

“…What is most striking, AgF 3 spontaneously decomposes thermally, while liberating F 2 at temperatures above − 20 • C (!) [34] (again, only several chemical systems can do the same). This means that Ag 3+ transfers its 4d holes back to F 2p manifold with enormous ease.…”

In this personal account, the author takes readers on the journey to "Silverland," i.e., the emerging field of electronic and magnetic materials based on divalent silver (Ag 2+ ). He blends historical background with the reasons which led him to become involved in this research, as well as to proposing (with Roald Hoffmann, 2001) that high-T C superconductivity might ultimately be observed in doped Ag 2+ fluorides. More recent experimental and theoretical findings related to novel compounds, and their electronic and magnetic structure, are presented.

“…The solidstate structure of AuF3 was first studied by X-ray powder diffraction, where it became apparent that the material was structurally very different from AuCl3 (33). This was later confirmed by a single crystal X-ray diffraction experiment (34,35). The structure consists of a fluorine bridged helical chain polymer ( Figure 1A), in which the chains are further cross-linked by weak fluorine-gold contacts (2.69 Å).…”
