The crystal structure of the title compound was determined in order to obtain structural information on a tetrapyrrole bearing meso-oxo-functions. C36H42N4O2T1C1 · CH3OH, P1̄, a = 10.358(2), b = 12.344(3), c = 15.490(3) Å, a = 84.36(2)°, β = 78.53(2)°, γ = 82.26(2)°, V = 1918.2(7) Å3, Z = 2, 130 K, R = 0.04 for 6749 reflections with I > 4σ(Ι). The structure consists of the penta-coordinated thallium ligated by the four nitrogens of the porphodimethene ligand and a chloride in the axial
