An Oxygen‐ peri ‐Bridged Quinolinium Cation and Its Monoradical Counterpart

Phosphorus peri-bridged acenaphthenes: efficient syntheses, characterisation and quaternization reactions.

Using a novel strategy, tertiary phosphines based on single atom peri-bridged acenaphthenes were prepared and characterized by multinuclear NMR and by X-ray diffraction.

Formation and structure of a stable monoradical cation by reduction of a diphosphafulvenium salt.

Oxygen and Cation Diffusion Processes in Oxygen Ion Conductors

We discuss oxygen and cation diffusion processes in oxygen ion conductors. While the high oxygen diffusivity determines the proper oxygen ion conductivity, slow cation diffusion processes are important for sintering and degradation processes. In the first part of the paper we discuss an analytical model for the ionic conductivity of a strongly acceptor doped, fluorite-type oxygen ion conductor,...

Cytotoxic and anticancer studies of an oxygen and nitrogen donor novel Schiff base ligand and its copper (II) complex

A selected solid complex of the Schiff base ligand derived from Glutaric anhydride with Cu(II) ion was synthesized and characterized by FT-IR, Electronic, ESR Spectral Analyses, Magnetic susceptibility and Molar Conductance Measurements. The disappearance of ν(O-H) hydroxyl band of the phenolic and the lowering shift of the stretching frequency of the ν(CH=N) azomethine band in the ligand after...

Exchange-coupled oxygen- and sulfur-bridged cyclopentadienyl-manganese(II) cages.

The trimetallic complex [{CpMn(μ-OSiPh3)2}2Mn] (1) and the heterocubane [CpMn(μ3-SSiPh3)]4 (2) are formed by deprotonation of Ph3SiQH (Q = O, S) by manganocene, or by transmetallation of manganocene by Ph3SiQLi. The Mn(II) centres in 1 and 2 are antiferromagnetically coupled, with J = −4.4 and −3.0 cm(−1) in 1 and 2, respectively (−2J formalism).
