Summary: This study presents a valence bond analysis of Ge-3(NH)(3) and explores the entire E-3(NH)(3) series (E=C, Si, Ge, Sn, Pb). The E-3(NH)(3) rings exhibit a nonbonded structure with localized pi-lone pairs on the N atoms, unlike the aromatic carbon rings with pi-delocalization. However, these molecules have significant covalent-ionic resonance energies, indicating the presence of stabilized pi-systems through charge-shift bonding. This analysis provides insights into the structure and pi-delocalization in germanazene and its substituted derivatives.

Summary: According to the Hume-Rothery rule, anions with a large difference in ionic radii cannot form solid solutions. However, this study demonstrates that Ba2H3X (X = CI, Br, or I) with a special structure can form trihalide solid solutions containing substantial amounts of each halogen. The analysis of synchrotron X-ray diffraction data reveals a significant deviation of the local structure from the average structural model for the solid solutions, which is mainly attributed to the different size variances of X- anions. Furthermore, the study shows that size-flexible H- anions play an important role in the formation of trihalide solid solutions.

Summary: The reactions between [Cp2Mo2(CO)(4)(mu,eta(2)-Sb-2)] (C) and Ag[TEF] in the presence of various N-donor ligands result in the selective formation of dimeric or tetrameric supramolecular coordination complexes and 1D or 2D coordination polymers. These compounds represent unique examples of supramolecular complexes incorporating both organometallic Sb-donor and organic N-donor ligands to stabilize metal ions. Notably, one of the formed compounds, the CP [Ag-4(eta(2 : 1)-C)(4)(L4)(4)](n)[TEF](4n), is an exceptional 1D polymer incorporating both N- and Sb-donor ligands as connectors for metal ions.

Summary: We have successfully synthesized two new dual-cation uranium oxide hydrate (UOH) materials, incorporating Cd2+ and K+ ions, and characterized them using single-crystal X-ray diffraction and other structural and spectroscopic techniques. The two materials differ in terms of structures, topology, and ratios of uranium to cations. The layered UOH-Cd shows a plate morphology with a U : Cd : K ratio of 3 : 1.5 : 1, while the framework-type UOF-Cd contains less Cd with a U : Cd : K ratio of 4.4 : 0.2 : 1 and forms needle-like crystals. Both structures feature beta-U3O8 type layers with a distinct uranium center lacking expected uranyl bonds, emphasizing the significance of the beta-U3O8 layer in the self-assembly and formation of various structural types. Importantly, this study demonstrates the potential to expand the synthesis of viable UOH phases by utilizing monovalent cation species (e.g. K+) as secondary metal cations, thereby advancing the understanding of these systems as alteration products in the vicinity of spent nuclear fuel in deep geological repositories.

Summary: This paper reports the design and synthesis of far-red emissive boryl-thiophene-BODIPY triads. The pi-conjugation length and electronic communication between borane and BODIPY moieties can be tuned by varying the size of the oligothiophene spacer in these triads. These triads exhibit intriguing triple emissions in the blue to far-red regions. Experimental and computational studies suggest that the multiple emissions in these triads are due to an inefficient transfer of energy from the boryloligothiophene to the BODIPY unit.
