%X The magnetic anisotropy of Mn(antipyrene)6(ClO4)2 below 20 K indicates that the zero-field splitting parameter (D) is about three times greater than obtained from e.p.r. measurements of manganese doped into a series of isomorphous host lattices. Shape anisotropy effects are significant unless spherical crystals are used. The interpretation of the magnetic anisotropy above 20 K is complicated by the large diamagnetic contribution from the ligands and it is suggested that there are significant differences in the orientation of the ligand molecules in the isomorphous manganese and magnesium complexes.
