BIS(TRIPHENYLPHOSPHINE)IMINIUM BIS(METHOX O)PHTHALOCYANINATO(2)FERRATE(III) - SYNTHESIS AND CRYSTAL-STRUCTURE

Chlorophthalocyaninato(2-)ferrate(III) reacts with bis(triphenylphosph ine)iminium hydroxide in methanol/acetone solution to yield blue cryst als of bis(triphenylphosphine)iminium bis(methoxo)phthalocyaninato (2- )ferrate(III). The complex salt crystallizes as an acetone/methanol so lvate ((PNP)-P-b)[Fe(OCH3)(2)pc(2-)].(CH3)(2)CO . 1.5 CH3OH in the tri clinic space group P (1) over bar(no. 2) with the cell parameters a = 13.160(5) Angstrom, b = 15.480(5) Angstrom, c = 17.140(5) Angstrom alp ha = 97.54(5)degrees, beta = 91.79(5)degrees, gamma = 95.44(5)degrees. The Fe atom is located in the centre of the pc(2-) ligand coordinatin g four isoindole N atoms (N-iso) of the pc(2-) ligand and two O atoms of the methoxo ligands in a mutual trans arrangement. The average Fe-O and Fe-N-iso distances are 1.887 and 1.943 Angstrom, respectively. Th e cation adopts the bent conformation (<P-N-P = 140.4(2)degrees) with P-N distances of 1.579(3) and 1.575(3) Angstrom.
