本文用温度跃变弛豫方法研究了Co（Ⅱ）、Ni（Ⅱ）和Zn（Ⅱ）单氨配合物在水溶液中的形成和解离动力学。评估的形成速率常数示出对应于涉及从水金属离子的解离的水作为速率决定步骤后的初始形成的外层复合物的机制。为了解释先前研究的多胺络合物的更快的形成速率，提出了内部共轭碱机制。
The kinetics of formation and dissociation have been studiedfor the monoammine complexes of Co (II), Ni (II), and Zn (II) in aqueous solution using the temperature-jump relaxation method. The evaluated formation rate constants are shown to correspond to a mechanism involving the dissociation of water from the aquometal ion as the rate-determining step following the initial formation of an outer-sphere complex. To account for the much faster formation rates of the previously studied polyamine complexes, an internal conjugate base mechanism is proposed.
