Abstract: In the title compound, [Li(C₁₂H₁₀O₂P)(C₄H₈O)]_n, the O atoms of adjacent and bridging diphenylphosphinate ligands and that from a tetrahydrofuran (thf) molecule are arranged in a tetrahedral manner around the Li atoms, resulting in a one-dimensional array (parallel to the a axis) of alternate eight-membered and rectangular planar four-membered rings [the two Li-O distances are 1.962  (6) and 1.991  (6)  Å, and the Li-O-Li and O-Li-O angles are 88.3  (2) and 91.7  (2)°, respectively]. The Li-O distances for the O atoms of the phosphinate ligand are 1.992  (6)  (for the -O atom) and 1.897  (6)  Å, and the distance from Li to the O atom of the thf ligand is 2.028  (6)  Å.
