Investigation of easy-plane magnetic anisotropy in P-ligand square-pyramidal Co-II single ion magnets

In this work we report two pentacoordinated Co-II-P4X1 Single Ion Magnets (SIMs) based on P-donor ligands. The tetradentate ligand tris[2-(diphenylphosphino) ethyl] phosphine allows the obtention of the isostructural square pyramidal [Co(PP3)Cl]center dot ClO4 (1) and [Co(PP3)Br]center dot ClO4 (2)...
