Chloroform was found to occupy the lattice of the protonated porphyrin and to promote crystallization of a different polymorphic form of a metalloporphyrin. The structure of 5,10,15,20-tetraphenylporphyrin-21,23-diium dichloride chloroform octasolvate, C(44)H(32)N(4)(2+)·2Cl(-)·8CHCl(3), (I), in the solid state is described and compared with related solvates. The porphyrin macrocycle displays a distorted saddle shape, with chloride anions above and below the ring. Seven chloroform molecules are bound via C-H···Cl hydrogen bonds, while the link with the eighth solvent molecule is weaker. A new monoclinic polymorph of (5,10,15,20-tetraphenylporphyrinato)copper(II), [Cu(C(44)H(28)N(4))], (II), crystallized from chloroform, is also presented.

The title complex, [Fe(C12H8N2)3]Cl2·6CH3OH, contains a slightly distorted octahedral [Fe(phen)3]2+ cation (phen is 1,10‐phenanthroline). Chloride anions and solvent methanol molecules form two distinct hydrogen‐bonded anionic clusters, formulated as [Cl(MeOH)2]− and [Cl(MeOH)4]−, which complete the crystal structure.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
