Abstract

The title complex, [Sn(IV)(C(44)H(28)N(4))(CNO)(OH)], exhibits substitutional disorder of the OH(-) and OCN(-) axial ligands. Thus, the cyanato-O ligand and the hydroxyl group bonded to the central Sn(IV) atom share statistically the axial position. The Sn(IV) ion is hexa-coordinated by the four N atoms of the pyrrole rings of the tetra-phenyl-porphyrin (TPP) and the O atoms of the two disordered OCN(-) and OH(-) axial ligands. The equatorial tin-pyrrole N atom distance (Sn-N(p)) is 2.100 (2) Å and the axial Sn-O(OCN) or Sn-O(OH) bond length is 2.074 (2) Å.
