Hydrogen bond synthons affect the coordination geometry of d10-metal halide complexes: synthetic methods, theoretical studies, and supramolecular architectures

The tendency of the pyrazine nitrogen atom to form hydrogen bond supramolecular synthons affects the coordination geometry of new d10-metal halide complexes which have been prepared by solution-based methods in comparison with solid-state reactions.

Aromaticity control via modifications of a macrocyclic frame: 5,6-dimethoxyphenanthriporphyrin and 5,6-dioxophenanthriporphyrin

Antiaromatic phenanthriporphyrin and nonaromatic 5,6-dioxophenanthriporphyrin reveal specific reactivity toward protic and Lewis acids yielding respectively nonaromatic and aromatic macrocycles.

Halogen bonded cocrystals of active pharmaceutical ingredients: pyrazinamide, lidocaine and pentoxifylline in combination with haloperfluorinated compounds

Six novel halogen-bonded cocrystals of active pharmaceutical ingredients with 1,4-diiodo- and 1,4-dibromotetrafluorobenzene have been synthesized.

Halogen bonding ofN-bromosuccinimide by grinding

Two halogen bonded cocrystals ofN-bromosuccinimide and 4,4′-bipyridine, with stoichiometric ratios 1 : 1 and 2 : 1, have been synthesized and characterized. We present the first mechanochemical cocrystallization ofN-bromosuccinimide.
