摘要：

During the growth of small colloidal silver clusters in aqueous solution, the trimer silver ion exhibits a remarkable behavior in that this species represents the changeover from pseudo-first-order reaction mechanisms to second-order mechanisms. The model for the molecular structure of the trimer silver ion which is proposed here on the basis of divalent silver explains this observation and the formation of "magic" clusters.
