Abstract

The rose-colored compound Mn5(BO3)3OH was synthesized under high-pressure/high-temperature conditions of 2.5 GPa and 973 K in a Walker-type multianvil press. Single-crystal X-ray structure determination yielded the non-centrosymmetric monoclinic space group Pm (no. 6) with the lattice parameters a = 329.71(1), b = 1384.92(5), c = 902.37(3) pm, and β = 107.92(1)°. The presence of the hydroxide group is ascertained by vibrational spectroscopy. Magnetization experiments in the range from 300 to 14 K revealed paramagnetic behavior with antiferromagnetic ordering below 14 K and an effective magnetic moment of 12.2 µB per formula unit. The acentric nature of the material was verified by second harmonic generation measurements, yielding a considerably strong intensity (Isample/Iquartz = 11.14). Additionally, thermal investigations showed a several-step transformation to Mn2OBO3 upon heating under air.
