描述了三胺 2: 6-二-2'-吡啶基吡啶 (2: 2': 2"-三吡啶基) 的许多反应。用碱性高锰酸盐氧化碱仅产生吡啶-2-羧酸，从而表明它是优先攻击的三个吡啶环的中心酮。三胺充当三齿基团并提供许多稳定且特征性的配位化合物。这组盐分为两个系列，每个金属原子分别含有一个和两个分子比例的碱基，第一个系列是单三齿型[M三基XI和[M三基X]X，其中M=铜、一价和二价银、锌、镉、汞、钯和铂。第二个系列是双三齿型，由通式3[M2三基X]表示。 [MBtripy] X,,wH,O，其中M=二价铁、二价和三价钴、镍、二价钌、二价锇和三价铬。
A number of reactions of the triamine 2: 6-di-2'-pyridylpyridine (2: 2': 2"-tripyridyl) are described. Oxidation of the base with alkaline permanganate yields only pyridine-2-carboxylic acid, thus indicating that it is the centralone of three pyridine rings which is preferentially attacked. The triamine acts as a tridentate group and furnishes many stable and characteristic co-ordination compounds. This group of salts is divided into two series which contain severally one and two molecular proportions of base to each atom of metal. The first series is of monotridentate types [M tripy XI and [M tripy X] X, where M= copper, univalent and bivalent silver, zinc, cadmium, mercury, palladium and platinum. Tervalent iridium chloride yields [IrCl, tripy]. The second series is of bistridentate type represented by the general formula3 [M 2tripyl X, and [MBtripy] X,, wH, O, where M= bivalent iron, bi-and ter-valent cobalt, nickel, bivalent ruthenium, bivalent osmium and tervalent chromium.
