Tetraaqualithium(I) bis(tropolonato-²O,O')lithate(I)

G. Steyl

Abstract: The title salt, [Li(H₂O)₄][Li(C₇H₅O₂)₂], which was synthesized by reacting equimolar quantities of lithium hydroxide and tropolone in water, consists of a hydrated lithium cation whose charge is balanced by a ditropolonatolithate. Both Li atoms exist in a tetrahedral geometry (the cation and anion lie on different sites of 222 symmetry). Hydrogen bonds link the cation and anion into a layer structure; - stacking [centroid-centroid distance 3.313 (2) Å] is observed with the tropolonate rings, the stacking allowing the formation of channels that facilitate the packing of the cations within them.
