Abstract

The title compound, [Co(C11H10N3O) 2]ClO4, designated [Co(L2)2]ClO 4, was synthesized by reaction of CoII with two molar equivalents of (2-pyridyl)bis(2-pyridylamino)methane (L1) under ambient conditions, whereby the divalent metal ion was oxidized concomitantly with oxygenation and deamination of the aminal polydentate ligand to generate the tridentate ligand anion (2-pyridyl)(2-pyridylamino)methanolate, L 2 -. In the X-ray crystal structure of the complex cation, [Co(L2)2]+, the two L2 - ligands are coordinated to the central cobalt(III) metal ion in a facial mode to afford a pseudooctahedral geometry. The four pyridyl N atoms constitute the equatorial plane on which the cobalt(III) ion lies; the methanolate O atoms occupy the axial positions.
