Abstract

Li₄Na₂CsB₇O₁₄ with unique edge-sharing [BO₄]⁵⁻ tetrahedra, an unprecedented [B₁₄O₂₈]¹⁴⁻ cluster, and high anisotropic thermal expansion has been obtained under atmospheric pressure conditions, indicating that high pressure is not essential for obtaining edge-sharing [BO₄]⁵⁻ tetrahedra-containing borates. In addition, Li₄Na₂CsB₇O₁₄ may be used as a thermal expansion material.
