Аннотация

A new hybrid material [BiF4BrBzTPP]2[Co(NCS)4] (1) (BiF4BrBzTPP+ = 2,6-bisfluoro-4-bromobenzyltriphenylphosphinium, NCS = isothiocyanate) is synthesized and characterized by elemental analyses, IR, UV spectra, ESI–MS, molar conductivity, single crystal X-ray diffraction and magnetic susceptibility measurements. Compound 1 crystallizes in the monoclinic space group C2/ c with a = 15.272(2) Å, b = 24.779(3) Å, c = 14.482(2) Å, β = 101.037(2), V = 5378.9(12) Å3Z= 4. The compound comprises two cations and one anion which exhibits a distorted tetrahedral coordination geometry. The short F⋯F, C⋯Br and N⋯Br interactions and C–H⋯S hydrogen bonds consolidate the stacking of the molecules. Magnetic susceptibility measurements in the temperature range 2–300 K show that 1 exhibits weak antiferromagnetic coupling behavior.
