Abstract

The M-II and M-III magnetic ions in the extended molecular network P(C6D5)(4)MnFe(C2O4)(3) form a two-dimensional honeycomb magnetic lattice. The Mn2+ and Fe3+ ions alternate in the extended network which is formed by the oxalate (C2O4) ligands. These hexagonal layers are separated and charge compensated by large [P(C6D5)(4)](+) ions, positioned in between the honeycomb layers. P(C6D5)(4)MnFe(C2O4)(3) orders magnetically at T-N = 27(1) K. A full neutron spin polarization study of the neutron scattering cross section has been carried out which allows the unambigious separation of the magnetic cross section from the total diffraction process. The magnetic structure can be described with the magnetic Shubnikov group R3c. The magnetic moments are antiferromagnetically aligned along the c axis while the Mn2+ and Fe3+ ions form an antiferromagnetic alignment on the honeycomb lattice.
