Confinement of C60 in an extended saddle shaped nickel(II) macrocycle
Abstract
Saddle shaped (5,14-dihydro-2,3,6,8,11,12,15,17-octamethyldibenzo[b,i][1,4,8,11]tetraazacyclotetradecine)nickel(II), Ni(OMTAA), acts as a divergent receptor molecule with C60 forming a 1∶1 complex in solution and in the solid state, isolated as [Ni(OMTAA)C60]·2CS2. The extended supramolecular array is based on linear chains of close contact C60 molecules [fullerene· · ·fullerene centroids 10.03(1) and 10.04(1) Å], and linear chains of π-stacked alternating molecules of C60 and Ni(OMTAA) with adjacent chains running in opposite directions.
