Abstract

1,2-Dichloroethane was found to stabilize the lattice of chloride anions associated with the protonated porphyrin of formula [C44H32N4]Cl2·4C2H4Cl2. The synthesis and X-ray characterization of this compound are reported and compared with analogous solvates. The porphyrin macrocycle displays a distorted saddle conformation, with chloride anions positioned above and below the mean plane of the ring, further surrounded by two dichloroethane molecules that stabilize the crystal packing. The Second-Harmonic Generation response was evaluated using the Kurtz–Perry powder technique with a ND:YAG laser (1064 nm).
