The results of studies of the structure of Mn2.25Co0.75BO5 using powder neutron diffraction are presented. To perform these studies, the crystals of ludwigite Mn2.25Co0.75BO5 were grown by the solution-melt method using a solvent based on Bi2Mo3O12 with a dilution of Na2CO3 carbonate. Boric acid H311BO3 was used as a boron-containing component. Measurements of powder neutron diffraction were carried out at a temperature of 100 K on a powder prepared by grinding grown single crystals. The spatial group and lattice parameters were determined by the Rietveld method using an experimentally obtained diffractogram. It is shown that the grown crystals Mn2.25Co0.75BO5 have the spatial group Pbam. The cobalt and manganese ion crystallographic positions have been determined from the powder neutron diffraction pattern analysis. The narrow throat mode was observed in the temperature dependence of the EPR spectra.
