Crystal and molecular structure of 6,13‐Di(ethoxycarbonyl)‐7,12‐dimethyl‐dibenzo [b.i.]‐1,4,8,11‐tetraaza[14]annulenato(2‐) nitrosocobaltat [C26H26O5N5Co] and the neutral ligand [C26H28O4N4]

This is the authors' abstract. We don't add key points for this paper.

Both title compounds crystallize in the orthorhombic space group Pnma with 4 formular units in the unit cell. The lattice parameters are: [C26H26O5N5Co], a = 8.589(4), b = 19.395(3), and c = 14.850(3) Å;[C26H28O4N4], a = 8.413(7), b = 19.166(4), and c = 14.807(28) Å. The crystal structures have been determined by direct methods and refined by full‐matrix least square calculations. The ligands have a pronounced saddle‐shaped conformation in each structure because of interactions of the methyl groups with the benzene rings. The overall conformations of the neutral ligand and the cobalt complex are remarkably similar.
