Title: Synthesis and crystal structure of a novel pentaborate, Na{sub 3}ZnB{sub 5}O{sub 10}

Abstract

A novel ternary borate, trisodium zinc pentaborate, Na{sub 3}ZnB{sub 5}O{sub 10}, has been prepared by solid-state reaction at temperature below 750deg. C. The single-crystal X-ray structural analysis showed that Na{sub 3}ZnB{sub 5}O{sub 10} crystallizes in the monoclinic space group P2{sub 1}/n with a=6.6725(7)A, b=18.1730(10)A, c=7.8656(9)A, {beta}=114.604(6){sup o}, Z=4. It represents a new structure type in which double ring [B{sub 5}O{sub 10}]{sup 5-} building units are bridged by ZnO{sub 4} tetrahedra through common O atoms to form a two-dimensional {sub {approx}}{sup 2}[ZnB{sub 5}O{sub 10}]{sup 3-}-layer that affords one-dimensional channels running parallel to the [101] direction. Symmetry-center related {sub {approx}}{sup 2}[ZnB{sub 5}O{sub 10}]{sup 3-} layers are stacked along the b-axis, with the interlayer void spaces and intralayer open channels filled by Na{sup +} cations to balance charge. The IR spectrum further confirms the presence of both BO{sub 3} and BO{sub 4} groups and UV-vis diffuse reflectance spectrum shows a band gap of about 3.2eV.
