Synthesis, structure and properties of Pb 2 CuB 2 O 6
2006
Single crystals of Pb2CuB2O6 were grown from a PbO/CuO/B2O3 flux, and crystallize in a monoclinic cell of dimensions a = 5.6311(6), b = 8.7628(9), c = 6.2025(6) A˚, and b = 115.7060(10)8 with Z = 2; the space group is P21/c (no. 14). The structure was determined from 662 unique reflections and refined to the final residuals R1 = 0.0217, wR2 = 0.0586. The structure is characterized by the two-dimensional layer of interconnected rectangular planar CuO4 and triangular planar BO3 groups. The results of quantitative analysis ICP, DTA, vibrational spectroscopy, and magnetic investigations are also presented. # 2006 Elsevier Ltd. All rights reserved.
