A new oxyborate Nd2Sr3Cu3O6(BO3)2 was prepared at 1030°C and 1 atm of O2, and examined by means of electron diffraction, high-resolution transmission electron microscopy (HRTEM), Rietveld analysis for the X-ray diffraction data and infrared spectroscopy. This compound crystallized in the tetragonal system (space group P4/nnc) with a=7.7671(1) and c=35.8284 Å. The crystal structure of Nd2Sr3Cu3O6(BO3)2 was explained as an alternative stacking of (BO3)(Sr, Nd)2CuO2 (B-1201 unit) layers and (BO3)Sr2NdCu2O4 (B-1212 unit) layers. The BO3 groups, having a triangular planar structure, were ordered between the CuO2 sheets.
