Abstract

Abstract : A new lead borate iodide, [O2 Pb3 ]2 (BO3 )I, exhibits 1∞[O2 Pb3 ] double chains and large birefringence. Abstract : A new lead borate iodide, [O2 Pb3 ]2 (BO3 )I, has been successfully synthesized by a facile hydrothermal reaction. It exhibits an infinite one-dimensional (1D) 1∞[O2 Pb3 ] double chain which is constructed from OPb4 oxygen-centered tetrahedra. The 1∞[O2 Pb3 ] double chains are further bridged by BO3 units via sharing oxygen atoms to form two-dimensional (2D) 2∞[(O2 Pb3 )2 (BO3 )] layers with the I − ions situated in the spaces between the layers. First principles calculations indicate that [O2 Pb3 ]2 (BO3 )I exhibits a birefringence of about 0.072@1064 nm which originates from the synergistic contributions of the Pb–O/I and BO3 units. The IR, UV-vis-NIR and EDS results, as well as TG-DSC curves were also discussed in detail.
