[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-.

标题化合物[Co(C11H10N3O)2] ClO4,命名为[Co(L2)2] ClO4,是通过Co(II)与两个摩尔当量的(2-吡啶基)双(2-吡啶基氨基)甲烷( L1)在环境条件下,由此二价金属离子与氨基多齿配体的氧合和脱氨合同时被氧化,以生成三齿配体阴离子(2-吡啶基)(2-吡啶基氨基)甲醇盐L2-。在络合阳离子[Co(L2)2] +的X射线晶体结构中,两个L2-配体以面部模式与中心钴(III)金属离子配位,以提供伪八面体几何形状。四个吡啶基N原子构成了钴(III)离子所在的赤道面;甲醇中的O原子占据轴向位置。
