The structure of bismuth triborate has been analyzed by the combination of neutron and X-ray diffraction on powder and on single-crystalline samples. Bismuth triborate exhibits a distinct anisotropic thermal expansion with the coefficient along a being negative over the wide temperature range studied, 20 to 800 K. The remarkable crystal structure of bismuth triborate with a netlike linkage of rigid borate units [BO3] and [BO4], is found to generate the uncommon thermal expansion behavior. Our investigations gave no evidence for a structural phase transition in bismuth triborate between 3.5 and 999 K at ambient pressure.
