A new quaternary rare earth borate, CsLi₂Gd₄(BO₃)₅

M.-J. Xia and R. K. Li

Abstract: Single crystals of caesium dilithium tetragadolinium pentaborate, CsLi₂Gd₄(BO₃)₅, were obtained by heating lithium and gadolinium in a caesium borate flux. The structure features chains of edge- and corner-sharing GdO_n polyhedra. These chains are interlocked to form [Gd₈O₁₆(BO₃)₂]^14- layers, which are connected by borate groups in the third dimension. The Li and Cs atoms occupy O₅ pyramids and large cages in the framework, respectively.
