Abstract

In this work, the encapsulation of [CdBr₆]^4- by six cations, [Co(dien)₂]³⁺ has been described with the help of single crystal X-ray structural study in the complex, mer-[Co(dien)₂]₂[CdBr₆]Br₂. The complex anion, [CdBr₆]^4- has been obtained through solution method while attempting to synthesize complex dianion, [CdBr₄]^2-. This newly synthesized complex has been initially characterized by elemental analyses and spectroscopic studies (IR, NMR and UV-Visible). IR and NMR studies have been used for the isomeric identification of [Co(dien)₂]³⁺. Single crystal X-ray structure determination has revealed the presence of two complex cations, [Co(dien)₂]³⁺, one complex anion, [CdBr₆]^4-, and two Br^- anions. The complex has crystallized in monoclinic crystal system with space group, P2₁/n. The study of intermolecular interactions has confirmed the stability of crystal structure through N-H type H-bonding interactions besides electrostatic forces of attraction.
