Crystal structure of (5-{3-[(1,4,7,10,13-pentaoxa-16-azacyclooctadecan-16-yl)carbonylamino]phenyl}-10,15,20-triphenylporphyrinato)cobalt(II)

Abstract

In the title compound, [Co(C57H52N6O6)], the central CoIIatom is coordinated by four pyrrole N atoms of the porphyrin core and one O atom of the crown ether. The complex has a distorted porphyrin core, with mean absolute core-atom displacements of 0.14 (10) (Ca), 0.20 (10) (Cb), 0.24 (4) (Cm) and 0.18 (10) Å (Cav), respectively. The axial Co—O bond length is 2.3380 (15) and the average Co—Npbond length is 1.968 (5) Å. Intramolecular N—H...O and intermolecular C—H...π interactions are observed.
