Abstract
The crystal structure of thallium(I)catena-polyphosphate, TlPO3, contains a polyphosphate chain extending parallel to [010] with a repeating unit of two phosphate tetrahedra. The TlIatom is located in-between the polyphosphate chains and is bonded by oxygen atoms in a distorted [6 + 1] coordination in the form of a monocapped prism, with the longest Tl—O bond to the bridging O atom of the polyphosphate chain. A quantitative structural comparison with isotypic RbPO3and CsPO3reveals that the usually pronounced stereoactivity of the 6s2lone pair at the TlIatom is not apparent in the case of TlPO3.
