Bis{3,5-di-tert-butyl-N-[(4-di-methylamino)phenyl]salicylaldiminato}cobalt(II)

摘要

In the title complex [systematic name: bis(2,4-di-tert-butyl-6-{N-[4-(dimethylamino)phenyl]carboximidoyl}phenolato)cobalt(II)], [Co(C23H31N2O)2], the cobalt(II) atom is coordinated by pairs of O and N atoms in a distorted tetrahedral coordination geometry. The dihedral angles formed by the aromatic rings of the same ligand are 51.99 (11) and 36.58 (9). The molecular conformation features weak intramolecular C—HO hydrogen bonds. In the crystal, inversion-related pairs of complex molecules are linked into dimers by weak C—H interactions. The methyl C atoms of tert-butyl groups have rotational disorder, with site occupancies of 0.647 (7) and 0.617 (6) for the major components and 0.353 (7) and 0.383 (6) for the minor components. One of the methyl C atoms of the dimethylamino groups is also disordered over two orientations, with an occupancy ratio of 0.75 (4):0.25 (4).
