Crystals of the title compound, [Li{OOP(O-2,6-iPr2C6H3)2}(CH3OH)3]·CH3OH or [Li(C24H34O4P)(CH3OH)3]·CH3OH, have been formed in the reaction between HOOP(O-2,6-iPr2C6H3)2 and LiOH in methanol. The title compound is of interest as it represents the first reported crystal structure of the family of lithium phosphate diesters. The {Li(CH3OH)3[O2P(O-iPr2C6H3)2]} unit displays the Li atom in a slightly distorted tetrahedral coordination environment and exhibits one intramolecular O—H...O hydrogen bond between a coordinating methanol molecule and the terminal non-coordinating O atom of the phosphate group. The unit is connected with two non-coordinating methanol molecules through two intermolecular O—H...O hydrogen bonds, and with a neighbouring unit through two other O—H...O interactions. These intermolecular hydrogen bonds lead to the formation of infinite chains along [100]. There are no significant interactions between the chains.
