抄録

Crystal structure of tetragonal YBa₂Cu_2.93O_6.38 has been determined by the single-crystal X-ray diffraction method. The space group is P4/mmm with lattice constants: a=3.860(1) Å, c=11.813(4) Å, and V=176.05(7) ų. The structure refinement has been successfully carried out with the final R value of 0.019(R_w=0.020). A difference-Fourier map reveals the existence of localized d-electrons around Cu2 atoms in the unit cell, although the electrons of Cul atoms have a spherical distribution.
