Trans-dihydroxo-[tetrakis(2,6-dichlorophenyl)porphinato]ruthenium(IV), ([Ru(OH)2(TDCPP)]) was prepared by meta-chloroperbenzoic acid oxidation of [Ru(CO)(TDCPP)] in dichloromethane-toluene, and its crystal structureis reported. Crystal data for [Ru(OH)2(TDCPP)].2toluene: C44H22N4O2Cl8Ru.2C7H8, orthorhombic, space group Pbca, a=13.149(1), b=19.893(2), c=21.093(2) ?, U=5517.3(2) ?**3, Z=4. The short axial Ru-O bond distance, 1.790(7) ?, is in the range expected for a double Ru(IV)-oxygenbond. Both hydroxo ligands are approximately located in the mean plane of two opposite dichlorophenyl groups. Full-matrix least-squares refinement of positional and thermal parameters, using 2368 unique reflections with F>2.5σ(F) led to R(F)=0.063; R(w)=0.066.
