Ontology highlight
ABSTRACT: Organic-inorganic hybrid materials based on divalent metal halides constitute versatile platforms for tuning their physicochemical properties, with potential applications in optoelectronics, energy storage, and dielectric devices. Here, we present the first synthesis and complete characterization of [(C4H9)4N]2CoBr4, a novel halogenocobaltate(ii) compound. Hirshfeld surface analysis and single-crystal X-ray diffraction reveal a monoclinic structure composed of layered tetrabutylammonium cations and tetrahedral [CoBr4]2- units stabilized by strong C-H⋯Br interactions. The integrity of the organic and inorganic components is verified by vibrational spectroscopy (FT-IR and Raman). DSC analysis revealed the existence
