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 ...

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 ...

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).

Exploring the Impact of Lone Pairs on the Structural Features of Alkaline‐Earth (A) Transition‐Metal (M,M’) Chalcogenides (Q) AMM'Q3

European Journal of Inorganic Chemistry, Volume 2022, Issue 28, October 11, 2022., 2022
The influence of lone pairs on structural characteristics was determined for the examples of quaternary alkaline‐earth (A) rare‐earth (Ln) copper tellurides, ALnCuTe3, by means of experimental as well as quantum chemical techniques. Abstract Understanding electronic structures is decisive for the design of solid‐state materials, as its knowledge is ...

Crystal Structures of the Perovskite‐Related System A/Rb/Cu(II)/Br (A=BA, Gu, PEA, 5‐AVA, H2en) with Winners, Losers and Compromises – Versatility from 0D to 3D on Different Levels

European Journal of Inorganic Chemistry, Volume 2022, Issue 18, June 27, 2022., 2022
By precipitation from aqueous HBr we obtained 12 new compounds of the ternary and quaternary systems RbBr/CuBr2, ABr/CuBr2, and ABr/RbBr/CuBr2 (A=organic cation). Their crystal structures were determined by single crystal measurements. The new compounds range from 0D to 3D structures with octahedral (4+2, 2+4) or tetrahedral surroundings of the Cu2 ...
