Contributionf r o m the Sterling Chemistry Laboratory, Yale University, New Haven, Connecticut. Received February 13, 1967 Abstract: The crystal and molecular structure of triclinic tetraphenylporphyrin (TPP) has been solved using X-ray crystallographic techniques. The molecule is centrosymmetrical with two independent pyrrole and phenyl groups. Although the individual pyrrole and phenyl groups are planar within the error of their determination (
