A sterically hindered and highly lipophilic metalloporphyrin: Crystal and molecular structure of meso-tetrakis(3,5-di-t-butylphenyl)porphyrin-iridium(III) carbonyl chloride
摘要:
The title complex was synthesized and characterized by single-crystal X-ray analysis. The iridium(III) atom is coordinated by four nitrogen atoms in a square-planar fashion with Ir-N = 2.04(1) angstrom, and the coordination sphere is completed by chloro and carbonyl ligands at the axial positions with Ir-Cl = 2.293(6), Ir-C = 1.95(2) angstrom and Cl-Ir-C = 172.7(6)-degrees. The porphyrin ring is nearly planar with the dihedral angle between adjacent pyrrole rings at only 1.2-degrees. The dihedral angles between the porphyrin ring and the phenyl rings lie in the range 68.3-81.8-degrees.
