Ag₁₂[Ge₉(Hyp)₂]₆ An Intermetalloid Cluster with Bis-Silylated Ge₉ Units. [PDF]

Angew Chem Int Ed Engl
The reaction of K2Ge9(Hyp)2 (Hyp = Si(SiMe3)3) with phosphine stabilized silver halides gives the new intermetalloid cluster Ag12[Ge9(Hyp)2]6 exhibiting a novel Ag12 core surrounded by six [Ge9(Hyp)2] units acting as ligands. Within the Ag12 core two different kinds of silver atoms are present underlining the intermetalloid character of the cluster ...

Defect Trapping and Phase Separation in Chemically Doped Bulk AgF₂. [PDF]

Inorg Chem, 2021
We report a computational survey of chemical doping of silver(II) fluoride, an oxocuprate analog. We find that the ground-state solutions exhibit strong tendency for localization of defects and for phase separation.

High-Pressure Synthesis of Antimony Nitride Sb₃N₅ and Polynitride Sb₂N₈ Featuring Single-Bonded N₈ ^10- Chains. [PDF]

Angew Chem Int Ed Engl
High‐pressure reactions between Sb and molecular nitrogen in a laser‐heated diamond anvil cell led to the formation of oC32‐Sb3N5 (51(1) GPa) and mP20‐Sb2(N8), (> 100 GPa). Both phases were identified by single‐crystal x‐ray microdiffraction and are fully corroborated by density functional theory calculations.

Synthesis and Characterization of [MF₅(terpy)]⁺ (M = Mo, W) Salts: Autoionization of MF₆ Induced by a Tridentate Ligand. [PDF]

Chemistry
The hexafluorides MoF6 and WF6 autoionize in the presence of the tridentate terpyridine ligand, yielding [MF5(terpy)]+[MF7]– (M = Mo, W). The octacoordinated [MF5(terpy)]+ cations adopt bicapped trigonal prismatic geometries. The [WF7]– can be substituted for [SbF6]– using SbF5SO2, whereas the reaction was unsuccessful for displacing the [MoF7]– anion.

Elucidating Ligand Exchange Dynamics of Hexacyanochromate-Based Redox Mediators in Aqueous Iron-Chromium Redox Flow Batteries. [PDF]

Angew Chem Int Ed Engl
The ligand exchange between cyanide and hydroxide in hexacyanochromate negolyte was caused by the disruption of coordination environment of the redox mediator ([Cr(CN)6]4‐/3−), with a critical factor as an elevated pH during electrochemical cycle. To mitigate this electrolyte co‐modulation strategy is introduced, optimizing the [OH−]/[CN−] ratios ...

Neutral Adducts of Molybdenum Hexafluoride: Structure and Bonding in MoF₆(NC₅H₅) and MoF₆(NC₅H₅)₂. [PDF]

Chemistry
Molybdenum hexafluoride was shown to form Lewis acid base adduct with the organic base pyridine, the first neutral transition metal adducts beyond those of WF6. The MoF6(NC5H5) and MoF6(NC5H5)2 adducts adopt capped trigonal prismatic geometries. The trigonal prismatic MoF6 moiety in the adducts can be explained by the high electrostatic potentials of ...

The Role of Lithium Ions on the Solubility of K₄E₄ in Ethylenediamine and the Oxidation of the Zintl Anions [E₄]^4- (E = Ge, Sn, Pb) as well as [Ge₉]⁴. [PDF]

Chemistry
The solubility of K4Ge4, K4Sn4, and K4Pb4 phases and oxidation of comprised four‐atom clusters in ethylenediamine (en) is induced by the addition of LiCl. The 119Sn NMR spectra of [Sn9]4− with Li+ and K+ counterions indicate a cation‐dependent change in both the chemical shift and coupling constant, strongly suggesting K+/[Sn9]4− ion pairing, which is ...

Interactions of Pyridine‐Based Organic Cations as Structure‐Determining Factors in Perovskite‐Related Compounds AxPb(II)yBrz

European Journal of Inorganic Chemistry, Volume 26, Issue 15, May 24, 2023., 2023
The crystal structures of 21 new pyridine‐based Pb(II)‐bromides show that there is a complex relationship between geometrical, steric and electronic aspects in the formation of N−H⋅⋅⋅Br bridges. The interactions also influence the linkage pattern of the PbBrx polyhedra and vice versa. Abstract We have synthesised and characterised 21 new ternary Pb(II)

Circularly polarized luminescence of lanthanide complexes: From isolated individuals, discrete oligomers, to hierarchical assemblies

InfoMat, Volume 5, Issue 3, March 2023., 2023
The inherent electric‐dipole‐forbidden and magnetic‐dipole‐allowed 4f → 4f transitions of Lanthanide(III) ions make their complexes as idea candidates to achieve higher glum values. This review summarizes the recent progress of the chiroptical properties of chiral lanthanide complexes, with special attention on their discrete oligomers and hierarchical

The Unconventional Cadmium Borosulfates Cd[B2O(SO4)3] and Cd4[B2O(SO4)6]

Zeitschrift für anorganische und allgemeine Chemie, Volume 648, Issue 21, November 15, 2022., 2022
Abstract Borosulfates are an expanding class of silicate‐analogous materials. We report the syntheses and crystal structures of two unconventional cadmium borosulfates. Cd[B2O(SO4)3] crystallises in a new structure type in space group Pnma (no. 62, a=896.92(8), b=1152.0(1), c=872.75(8) pm, 1380 refl., 94 ref. param., wR2=0.112).
