Abstract: | Tetra(n-butyl)ammonium Phthalocyaninato(2–)lithate Tetrahydrofurane and Bis(tetra(n-butyl)ammonium) Phthalocyaninato(2–)lithate Fluoride Hydrate; Synthesis and Crystal Structure Dilithiumphthalocyaninate(2–) reacts with excess tetra(n-butyl)ammonium fluoride trihydrate to yield a mixture of blue tetra(n-butyl)ammonium phthalocyaninato(2–)lithate tetrahydrofurane and bis(tetra(n-butyl)ammonium) phthalocyaninato(2–)lithate fluoride hydrate. The latter crystallizes triclinic with crystal data: a = 8.6480(1) Å; b = 12.620(2) Å; c = 14.866(5) Å; α = 82.44(2)°; β = 87.01(2)°; γ = 75.02°; space group P1 ; Z = 1. Fluoride is not coordinated to lithium. On the contrary, a double-salt is formed, which consists of alternating layers of cations and anions. This arrangement opens a cavity in the centre of the unit cell which shares statistically a fluoride and a disordered fluoride hydrate. Pure tetra(n-butyl)ammonium phthalocyaninato(2–)lithate is obtained as a tetrahydrofurane solvate by the reaction of dilithiumphthalocyaninate(2–) with tetra(n-butyl)ammonium bromide in tetrahydrofurane. The solvate crystallizes monoclinic with crystal data: a = 12.455(5) Å; b = 23.396(5) Å; c = 16.120(5) Å; β = 94.986(5)°; space group P2/c1; Z = 4. |
