Synthesis and characterization of neodymium oxyhydroxide crystals

Single crystals of neodymium oxyhydroxide NdOOH were grown using an electrochemical method. Crystals having a maximum size of about 2 mm in length were grown. The structure was identified by single crystal X-ray diffraction and the refinement converged to R1 = 0.0170 and wR1 = 0.0426. NdOOH crystall...

Description
Summary:Single crystals of neodymium oxyhydroxide NdOOH were grown using an electrochemical method. Crystals having a maximum size of about 2 mm in length were grown. The structure was identified by single crystal X-ray diffraction and the refinement converged to R1 = 0.0170 and wR1 = 0.0426. NdOOH crystallizes in a monoclinic structure of the space group P2 1/ m with lattice parameters of a = 4.3896(2) Å, b = 3.8319(2) Å, c = 6.2424(3) Å, and β = 108.131(2)°, and Z = 2. The resistivity shows semiconductor-like characteristics with the activation energy E a = 0.93 eV. No magnetic order was found down to 5 K.
