Two pseudopolymorphs of LiCl trimers with semicubane structures.
The title compounds, trichlorido(mu3-triethylphosphine oxide-kappa(3)O:O:O)tris(mu2-triethylphosphine oxide-kappa(2)O:O)trilithium(I) toluene solvate, [Li3Cl3(C6H15OP)4] x C7H8, (I), and trichlorido(mu3-triethylphosphine oxide-kappa(3)O:O:O)tris(mu2-triethylphosphine oxide-kappa(2)O:O)trilithium(I), [Li3Cl3(C6H15OP)4], (II), adopt separated semicubane structures in the solid state which are the first such structures to be reported for LiCl solvates. One triethylphosphine oxide ligand bonds via its O atom to the three Li atoms in a mu3 manner, while the other three triethylphosphine oxide ligands bridge three Li atoms in mu2 manners. The Cl atoms are in terminal instead of bridging positions, which is rather unusual for lithium chloride solvates.
