Synthesis and Crystal Structure of Tetra(n-butyl)ammonium Hydroxomethoxophthalocyaninato(2-)iridate(III) Methanol Solvate
Abstract
Bis(phthalocyaninato(2-)iridium(II)) reacts in methanol with excess tetra(n-butyl)ammonium hydroxide to yield tetra(n-butyl)ammonium hydroxomethoxophthalocyaninato(2-)iridate(III). The complex salt crystallizes as a methanol solvate in the monoclinic space group P21/n(No. 14) with cell parameters a = 12.510(1) Å, b = 19.561(3) Å, c = 18.489(2) Å, = 90.42(1) °, Z = 4. The Ir atom is hexacoordinated with four isoindole N atoms (Niso) of the severely saddled pc ligand and two O atoms of the hydroxide (O1) and methoxide (O2) ligand respectively in a mutual trans arrangement. The average Ir-Niso distance is 1.981(5) Å, the Ir-O1 distance 2.038(7) Å and the Ir-O2 distance 2.061(6) Å. The O atom of the solvate (O3) is bound to O2 by a strong hydrogen bond with an O2-O3 distance of 2.60(1) Å.
