Indium(III) porphyrins containing metal-sulphur bonds (L = porphyrinate, R = alkyl or aryl) are reported.The photochemical oxidation of these leads to the corresponding sulphinatoindium(III) pophyrins .The insertion of sulphur dioxide between the indium atom and the alkyl or aryl group of also gives rise to the sulphinato-compounds.The latter can easily be oxidised to the corresponding sulphonato-complexes.The crystal structure of the title compound *2C2H4Cl2 has been determined by X-ray diffraction methods.Crystals are triclinic, space group PI, with a = 13.027(2), b = 13.284(2), c = 14.029(2) Angstroem, α = 68.82(2) deg, β = 85.31(2) deg, γ = 88.13(2) deg, and Z = 2.The structure has been solved by Patterson and Fourier methods and refined by full-matrix least-squares calculations to R = 0.063.This complex crystallises as a one-dimensional polymer, parallel to the c axis.The indium atom lies rigorously in the four-nitrogen plane and the structure may be discribed as the close packing of (1+) and (1-) ions.A high-resolution n.m.r. study shows that this structure is destroyed in solution at low concentrations.
