title: Bis-(methane-sulfonato-κO)(5,10,15,20-tetra-phenyl-porphyrinato-κ(4)N,N',N'',N''')tin(IV) chloro-form tris-olvate.
abstract: In the crystal structure of the title compound, [Sn(C(44)H(28)N(4))(CH(3)O(3)S)(2)]·3CHCl(3), the Sn(IV) ion is located on an inversion center and is octa-hedrally coordinated. The porphyrin N atoms occupy the equatorial positions while the axial positions are occupied by the O atoms of the methane-sulfonate anions. The phenyl rings make dihedral angles of 77.02 (13) and 87.89 (14)° with the porphyrin ring. Of the three solvent chloro-form mol-ecules, one is disordered over a twofold rotation axis. In the crystal a three-dimensional assembly is accomplished via C-H⋯O hydrogen bonds between the H atoms of the phenyl groups in the porphyrin ring and the O atoms of the methane-sulfonate ligands.
