Synthesis, Crystal Structure, Crystal Chemistry, and Magnetic Properties of PbMBO4 (M = Cr, Mn, Fe): A New Structure Type Exhibiting One- Dimensional Magnetism

The crystal chemistry of a new structure type found in the Pb−M−B−O system, PbMBO4 (M = Al, Ga), was extended to include M = Cr, Mn, and Fe. Extension to other trivalent ions, such as Ti, V, Co, Sc, In, and Y, failed for various reasons. Single crystals were grown from a PbO flux for M = Mn and Fe and the crystal structures were solved from X-ray single-crystal diffraction data. For M = Cr, the structure was refined from neutron powder …
