Bis(methanesulfonato-κO)(5,10,15,20-tetraphenylporphyrinato-κ4N,N′,N′′,N′′′)tin(IV) chloroform trisolvate

Abstract

In the crystal structure of the title compound, [Sn(C44H28N4)(CH3O3S)2]·3CHCl3, the SnIV ion is located on an inversion center and is octahedrally coordinated. The porphyrin N atoms occupy the equatorial positions while the axial positions are occupied by the O atoms of the methanesulfonate anions. The phenyl rings make dihedral angles of 77.02 (13) and 87.89 (14)° with the porphyrin ring. Of the three solvent chloroform molecules, 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 methanesulfonate ligands.
