Lithium‐ion mobility in Li6B18(Li3N) and Li vacancy tuning in the solid solution Li6B18(Li3N)1−x(Li2O)x

All-solid-state batteries are promising candidates for safe energy-storage systems due to non-flammable solid electrolytes and the possibility to use metallic lithium as an anode. Thus, there is a challenge to design new solid electrolytes and to understand the principles of ion conduction on an atomic scale. We report on a new concept for compounds with high lithium ion mobility based on a rigid open-framework boron structure. The host–guest structure Li6B18(Li3N) comprises large hexagonal pores filled with urn:x-wiley:14337851:media:anie202213962:anie202213962-math-0001 Li7N] strands that represent a perfect cutout from the structure of α-Li3N. Variable-temperature 7Li NMR spectroscopy reveals a very high Li mobility in the template phase with a remarkably low activation energy below 19 kJ mol−1 and thus much lower than pristine Li3N. The formation of the solid solution of Li6B18(Li3N) and Li6B18(Li2O) over the complete compositional range allows the tuning of lithium defects in the template structure that is not possible for pristine Li3N and Li2O

Acquisition and Evolution of Plant Pathogenesis–Associated Gene Clusters and Candidate Determinants of Tissue-Specificity in Xanthomonas

is a large genus of plant-associated and plant-pathogenic bacteria. Collectively, members cause diseases on over 392 plant species. Individually, they exhibit marked host- and tissue-specificity. The determinants of this specificity are unknown. lineage. genome and indicate that differentiation with respect to host- and tissue-specificity involved not major modifications or wholesale exchange of clusters, but subtle changes in a small number of genes or in non-coding sequences, and/or differences outside the clusters, potentially among regulatory targets or secretory substrates

NEOTROPICAL XENARTHRANS: a data set of occurrence of xenarthran species in the Neotropics

Xenarthrans – anteaters, sloths, and armadillos – have essential functions for ecosystem maintenance, such as insect control and nutrient cycling, playing key roles as ecosystem engineers. Because of habitat loss and fragmentation, hunting pressure, and conflicts with 24 domestic dogs, these species have been threatened locally, regionally, or even across their full distribution ranges. The Neotropics harbor 21 species of armadillos, ten anteaters, and six sloths. Our dataset includes the families Chlamyphoridae (13), Dasypodidae (7), Myrmecophagidae (3), Bradypodidae (4), and Megalonychidae (2). We have no occurrence data on Dasypus pilosus (Dasypodidae). Regarding Cyclopedidae, until recently, only one species was recognized, but new genetic studies have revealed that the group is represented by seven species. In this data-paper, we compiled a total of 42,528 records of 31 species, represented by occurrence and quantitative data, totaling 24,847 unique georeferenced records. The geographic range is from the south of the USA, Mexico, and Caribbean countries at the northern portion of the Neotropics, to its austral distribution in Argentina, Paraguay, Chile, and Uruguay. Regarding anteaters, Myrmecophaga tridactyla has the most records (n=5,941), and Cyclopes sp. has the fewest (n=240). The armadillo species with the most data is Dasypus novemcinctus (n=11,588), and the least recorded for Calyptophractus retusus (n=33). With regards to sloth species, Bradypus variegatus has the most records (n=962), and Bradypus pygmaeus has the fewest (n=12). Our main objective with Neotropical Xenarthrans is to make occurrence and quantitative data available to facilitate more ecological research, particularly if we integrate the xenarthran data with other datasets of Neotropical Series which will become available very soon (i.e. Neotropical Carnivores, Neotropical Invasive Mammals, and Neotropical Hunters and Dogs). Therefore, studies on trophic cascades, hunting pressure, habitat loss, fragmentation effects, species invasion, and climate change effects will be possible with the Neotropical Xenarthrans dataset

Derivatization of Phosphine Ligands with Bulky Deltahedral <i>Zintl</i> ClustersSynthesis of Charge Neutral Zwitterionic Tetrel Cluster Compounds [(Ge₉{Si(TMS)₃}₂)^<i>t</i>Bu₂P]M(NHC^Dipp) (M: Cu, Ag, Au)

Reactions of silylated clusters [Ge₉{Si­(TMS)₃}₃]⁻ or [Ge₉{Si­(TMS)₃}₂]²⁻ with dialkylhalophosphines R₂PCl (Cy, ^<i>i</i>Pr, ^<i>t</i>Bu) at ambient temperature yield the first tetrel <i>Zintl</i> cluster compounds bearing phosphine moieties. Varying reactivity of the dialkylhalophosphines toward the silylated clusters is observed depending on the bulkiness of the phosphine’s alkyl substituents and on the number of hypersilyl groups at the tetrel cluster. Reactions between phosphines with small cyclohexyl- (Cy) or isopropyl- (^<i>i</i>Pr) groups and the tris-silylated cluster [Ge₉{Si­(TMS)₃}₃]⁻ yield the novel neutral cluster compounds [Ge₉{Si­(TMS)₃}₃PR₂] (R: Cy (<b>1</b>), ^<i>i</i>Pr (<b>2</b>)) with discrete Ge–P <i>exo</i> bonds. By contrast, the bulkier phosphine ^<i>t</i>Bu₂PCl does not react with [Ge₉{Si­(TMS)₃}₃]⁻ due to steric crowding. However, the reaction with the bis-silylated cluster [Ge₉{Si­(TMS)₃}₂]²⁻ yields the novel cluster compound [Ge₉{Si­(TMS)₃}₂P^<i>t</i>Bu₂]⁻ (<b>3</b>). Subsequent reactions of compound <b>3</b> with NHC^DippMCl (M: Cu, Ag, Au) yield the charge neutral zwitterionic compounds [(Ge₉{Si­(TMS)₃}₂)^<i>t</i>Bu₂P]­M­(NHC^Dipp) (M: Cu, Ag, Au) (<b>4</b>–<b>6</b>), in which compound <b>3</b> acts as a phosphine ligand bearing a bulky tetrel <i>Zintl</i> cluster moiety. Compounds <b>4</b>–<b>6</b> also represent the first uncharged examples for 3-fold substituted tetrel <i>Zintl</i> clusters
