[Co(L2)2]ClO4, was synthesized by reaction of Co(II) 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, L2-.
