Özet

The title molecule, 2,7,12,17-tetrakis(4-chloro-phenyl)-21,22,23,24-tetraazapentacyclo[I 6.2. 1.1(3,6.-1(8,11.)1(13,16]tetracosa-1,3(22),4,6,8,10,12,14,16(4),17,-19-undecaene, is crystallographically centrosymmetric and the dihedral angle between the two pyrrole ring planes is 5.0 (4)-degrees . The molecular structure is a consequence of steric hinderances between the a-H atoms of the pyrrole and the ortho-H atoms of the phenyl rings. The dihedral angles between the pyrrole and phenyl rings are 54.8 (4) and 111. 1 (3)-degrees, respectively. The sums of the angles around meso-C atoms are -360-degrees and the average bond length between meso and adjacent macrocyclic ring C atoms is 1.398 (6) angstrom.
