The Role of Coulomb Interactions for Spin Crossover Behaviors and Crystal Structural Transformation in Novel Anionic Fe(III) Complexes from a π-Extended ONO Ligand

Crystals, 2016
To investigate the π-extension effect on an unusual negative-charged spin crossover (SCO) FeIII complex with a weak N2O4 first coordination sphere, we designed and synthesized a series of anionic FeIII complexes from a π-extended naphthalene derivative ...

Bis(4-methoxybenzylammonium) tetrabromidocadmate(II)

IUCrData, 2018
The asymmetric unit of the organic–inorganic hybrid salt, (C8H12NO)2[CdBr4], consists of two 4-methoxybenzylammonium cations and one [CdBr4]2− anion. The cations and anions are connected by a complex series of N—H...Br and C—H...Br hydrogen bonds. No π–π
