Abstract
Two new cocrystals, 2C70 • 3CoII(OEP) • 2CHCl3 (1) (OEP is the dianion of octaethylporphyrin) and C70 • 2ZnII(OEP) •o-xylene (2), with a clamshell arrangement of two porphyrins about a central C70 have been grown and structurally characterized. 2C70 • 3CoII(OEP) • 2CHCl3 (1) possess a unique double clam shell arrangement in which there are two distinct compartments for the fullerenes and a distorted 3CoII(OEP) molecule that is sandwiched between two C70 molecules. 2ZnII(OEP) •o-xylene (2) has a simple clam shell arrangement of two 2ZnII(OEP) molecules surrounding the C70 molecule, with these clam shells arranged into chains through close face-to-face contact between the porphyrins. In contrast, C70•ZnII(OEP)•1.5 p-xylene (3) has a more common structure with the C70 molecule in close proximity to only one ZnII(OEP) molecule.
