Controlling the Guanidinium Cation Rotation by Cation–π Interactions

Angewandte Chemie International Edition, EarlyView.
A lanthanide π‐container has been employed to trap a guanidinium cation inside the aromatic cavity by cation–π interactions. X‐ray crystallography and solid‐state nuclear magnetic resonance (NMR) spectroscopy at fast magic‐angle spinning (MAS) frequencies have been utilized to probe the underlying host–guest interactions.

First Evidence for Ozonido‐TMC Complexes of Iron and Cobalt

Angewandte Chemie International Edition, EarlyView.
Reaction of ozone with iron(II) complexes [(TMC)Fe(OTf)]BArF, [(D12‐TMC)Fe(OTf)]BArF, and cobalt(II) complexes [(TMC)Co(OTf)]BArF, [(D12‐TMC)Co(X)]BArF (X = OTf, F) gives ozonido and oxido complexes at temperatures as low as –155°C in a 4:1 mixture of 2‐Me‐THF and THF. ABSTRACT We present compelling evidence for the first Fe‐ and Co‐ozonido complexes: [

2,4-Dimethylanilinium perchlorate [PDF]

Acta Crystallographica Section E Structure Reports Online, 2010
The crystal packing of the title compound, C(8)H(12)N(+)·ClO(4) (-), is stabilized by N-H⋯O hydrogen bonds, the protonated amine group acting as a hydrogen-bond donor with the perchlorate O atoms as acceptors. These connect neighbouring cations and anions, forming a two-dimensional network.

One‐Step Electrodeposition of Iron Oxyhydroxide Onto 3D Porous Graphene Substrates for on Chip Asymmetric Micro‐Supercapacitors

Batteries &Supercaps, Volume 8, Issue 3, March 2025.
A micro‐supercapacitor with electrodeposited iron oxyhydroxide (FeOOH) as the negative electrode and birnessite manganese oxide (MnO2) as the positive electrode achieves a 2 V working voltage, stable cycling in an aqueous electrolyte, and high energy and power densities of 21 μWh cm‐2 and 2.5 mW cm‐2 respectively.

4-Acetylpyridinium perchlorate [PDF]

Acta Crystallographica Section E Structure Reports Online, 2009
In the crystal of the title mol-ecular salt, C(7)H(8)NO(+)·ClO(4) (-), the ions are linked by N-H⋯O hydrogen bonds, resulting in chains propagating in [010]. The packing is reinforced by C-H⋯O inter-actions.
