Abstract

Three penta-coordinate Co²⁺ complexes with halide substitutes were synthesized. Their zero-field splitting (ZFS) parameters were determined by fitting dc magnetic data and far-infrared magneto-transmission spectra. The results gave an unusual case that complexes with heavier halide atoms bear smaller ZFS parameters.
