Abstract
Crystals of C60·PtII(OEP)·2(C6H6), TCNQ·CuII(OEP), TCNQ·H2(OEP), TCNQ·2CuII(OEP), TCNQ·2ZnII(OEP) and TNFM·CoII(OEP) [OEP is the dianion of octaethylporphyrin, TCNQ is 7,7,8,8-tetracyanoquinodimethane, TNFM is (2,4,7-trinitrofluorenylidene)malonitrile] have been obtained by diffusion of a solution of the porphyrin as donor into a solution of the respective acceptor molecule. The structure of C60·PtII(OEP)·2(C6H6) consists of an ordered C60 cage nestled against the platinum porphyrin which makes close face-to-face contact with another PtII(OEP) molecule. In contrast, there are no close face-to-face contacts between porphyrins in the crystal structures of TCNQ·CuII(OEP), TCNQ·H2(OEP), and TNFM·CoII(OEP). These compounds consist of classical donor-acceptor stacks of interleaved porphyrin and TCNQ or TNFM molecules with separations of ca. 3.3 Å between adjacent molecules. However with TCNQ·2CuII(OEP) and TCNQ·2ZnII(OEP) the structures involve TCNQ (A) and MII(OEP) (D) molecules that crystallize in stacks with a DDA(DDA)nDDA arrangement. Within these stacks there are pairwise contacts between MII(OEP) molecules and these pairs are compared to those found in C60·PtII(OEP)·2(C6H6) and related fullerene-containing crystals.
