[O2Pb3]2(BO3)I: a new lead borate iodide with 1[O2Pb3] double chains

Author affiliations


A new lead borate iodide, [O2Pb3]2(BO3)I, has been successfully synthesized by a facile hydrothermal reaction. It exhibits an infinite one-dimensional (1D) 1[O2Pb3] double chain which is constructed from OPb4 oxygen-centered tetrahedra. The 1[O2Pb3] double chains are further bridged by BO3 units via sharing oxygen atoms to form two-dimensional (2D) 2[(O2Pb3)2(BO3)] layers with the I ions situated in the spaces between the layers. First principles calculations indicate that [O2Pb3]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.
