The new compound BaBe2(BO3)2 is readily prepared by a solid-state reaction. It crystallizes in the orthorhombic space group Fddd (Z = 8) in a cell of dimensions a = 11.725(2) angstrom, b = 13.004(1) angstrom, c = 6.286(1) angstrom, and V = 958.4(2) angstrom3. Residuals from least-squares refinement with 1689 unique reflections are R = 0.024 and R(w) = 0.042. The structure is composed of two interpenetrating polyhedral frameworks. A beryllium-borate matrix containing dimers of edge-sharing Be-centered tetrahedra linked via regular, planar triangular BO3 groups is penetrated by a framework constructed from Ba-centered dodecahedra sharing multiple edges. The optical emission characteristics of samples doped with the ions Eu2+ and Eu3+ are reported.
