Abstract: 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) complexes. Consistent theoretical and experimental studies indicate that these complexes have a high spin (S = 3/2) ground state and suggest that the relaxation dynamics is governed by ground state quantum tunneling, whereas its temperature dependence is directed by optical or acoustic Raman processes.
