The lithium terbium polyphosphate LiTb(PO3)4 was prepared by the flux method using a large excess of H3PO4. It was structurally characterized by single‐crystal X‐ray diffraction and found to be isotypic with LiYb(PO3)4. The basic structural units are endless spiral chains, (PO3)n, along the b‐axis direction. The Li+ and Tb3+ cations alternate on twofold axes and are four‐ and eight‐coordinated, respectively. The results of an optical study of this material are also given and discussed.
