- Abstract
A new hybrid material [BiF4BrBzTPP][Co(NCS)] ( 1) (BiF4BrBzTPP = 2,6-bisfluoro-4-bromobenzyl-triphenylphosphinium, 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) Å, Z = 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.
