摘要：

A new ternary borate, Pb3Cd3(BO3)(4), has been synthesized by solid-state reaction at 530 degrees C. The compound crystallizes in the hexagonal space group P6(3)/m with a = 9.946(4), c = 7.003(5) angstrom, and Z = 2. The crystal structure consists of one-dimensional (1D) long [PbO5](infinity) tubes. The tubes are further connected by BO3 to generate a three-dimensional framework with the six-member tunnels along the c axis, where Cd atoms locate and the CdO6 octahedra form 1D chain. The IR spectrum confirms the presence of BO3 unit. The UV-Vis-IR diffuse reflectance spectrum exhibits a band gap of about 3.56 eV. The DSC analysis suggests that Pb3Cd3(BO3)(4) is an incongruent melting compound. Crown Copyright (C) 2011 Published by Elsevier B. V. All rights reserved.
