N2 - A new lithium borate, Li3B11O18, was synthesized by crystallization from glass, containing an excess of B2O3. The compound crystallizes monoclinic, P2 1/a, Z = 4, a = 9.766(5) Å, b = 7.849(5) Å, c = 17.899(9) Å, β = 100.96(5) °, V = 1347.0(13) Å3 (R = 0.06, wR = 0.12). The structure is based upon two interpenetrating frameworks formed by triborate and pentaborate groups. The thermal behav -iour of Li3B11O18 was studied using DTA, DSC, and high- temperature XRD. Highly anisotropic thermal expansion and a new high-temperature phase were observed.
