Cation-dependent reactions "[SbBr ] +Br +HBr+CationBr " result in the formation of bromide/polybromide complexes with zero-, one-, two-, or three-dimensional supramolecular frameworks and different Br/Sb ratios (up to 11). Seven new compounds representing six structural types were characterized by XRD and thermogravimetric analysis and DFT calculations enabled estimation of the energies of the Br⋅⋅⋅Br contacts (1.1-4.6 kcal mol ).

Halogen bonding within bromo- and polybromoantimonates(v).

Three complexes [Co(2-XPy)2Cl2] (X = Cl, Br, and I) were prepared and characterized, representing a rare case of isostructurality within the Cl-Br-I row. The nature of halogen bonding (XB) in a solid state was studied by DFT calculations, revealing a tendency of XB energy growth for heavier halogens.

Structural characterization of pentaiodobenzoic acid (PIBA) and its salts was performed for the first time.

Reactions of [Sb III Br 6 ] 3with Br 2 in HBr in the presence of N-substituted quinolinium or isoquinolinium cations result in new complexes of hexabromidoantimonates of Sb V and their polybromide adducts: (N-MeQuin) 2 {[SbBr 6 ](Br 3 )} (1), * Dr. S.
