Polymorphie, Leitfähigkeit und Kristallstrukturen von Oxo-phthalocyaninato-titan(IV)

Oxo-phthalocyaninato-titan(IV) (PcTiO) shows weak electrical conductivity of 5 · 10~ Ω" 1 cm" 1 at room temperature. Doping of PcTiO with I2 is accompanied by an increase of conductivity up to 5· 10" Ω " 1 cm" 1 . PcTiO was found to exist in two modifications built up by monomeric complexes: Phase I crystallizes monoclinic in the space group Ρ 2 l /c with the lattice constants a = 1341.1(6) pm, b = 1323.0(3) pm, c = 1381.0(4) pm, β = 103.72(3)°, Ζ = 4. Phase II forms a triclinic structure in space group PT and an unit cell of dimensions a = 1216.6(4)pm, b = 1258.4(5)pm, c = 864.1 (3)pm, α = 96.28(3)°, β = 95.03(4)°, y = 67.86(4)°, Ζ = 2. In both modifications the Ti-atom exhibits a square pyramidal coordination with a short Ti — Ο distance of 165 pm and 163 pm, respectively. Close contacts exist between the phthalocyaninato planes of neighbouring molecules.
