    Abstract

    The first trigonal bipyramidal Fe(ii) complex to display slow relaxation of magnetisation has been isolated, with this behaviour found to arise through a combination of a large magnetic anisotropy (D = −27.5 cm−1) and a pseudo-D3h symmetry at the Fe(ii) centre, as investigated through ab initio and magnetic studies.
