Synthesis, characterisation and crystal structure of 2-aminopyridinium (2-amino-5-bromopyridine)tribromocuprate(II) and bis(2-aminopyridinium) tetrabromocuprate(II)

Crystal structure and spectroscopic study of bis-tetrapropylammonium hexachlorodicuprate(II), [N(C3H7)4]2Cu2Cl6

“…The Cu-Cl bond distances are in the range of 2.2046(6)-2.3231(6) Å for the Cu2Cl6 2-anion. These bond distances fall in the range reported previously for compounds containing Cu-Cl bonds [24][25][26][27][28]. The Cl-Cu-Cl angles are present in two distinguished sets.…”

Synthesis, Crystal Structure and Infrared Characterization of Bis(4-dimethylamino-pyridinium) Tetrachlorocuprate

“…The control of these interactions will be important for the design of materials with specific types of properties such as conductivity or magnetic behavior [8]. Several works were focused on copper (II) halides to study the influence of the organic cation features on the packing interactions that govern the structural organization and consequently on the properties of this kind of complex [9] [10]. Recently, some studies have examined how metal halide oligomers can be tied together via pyridinium derivative cations into chains, layers, etc.…”

Tetrahalidocuprates(ii)—structure and EPR spectroscopy. Part 1: Tetrabromidocuprates(ii)

“…As a result, some tetrahalidocuprate(II) complexes were already examined by EPR spectroscopy. 9,[54][55][56][57][58] The recent past has seen an increasing interest in halidocuprate(II) and EPR spectroscopy investigations supported by X-ray structure determination on doped crystals, 59 powders of single crystals with different and somewhat sterically demanding cations, [60][61][62][63][64] and single crystals. 65 Compared to chloridocuprate(II) complexes, there is currently relatively little knowledge on the bromide complexes.…”
