合成了三种新的DOTAM（1，4，7，10-tetrakis（acetamido）-1，4，7，10-tetraazacyclodecane）配合物：[Co（DOTAM）] Cl 2·3 H2O，[Ni（DOTAM）] Cl 2·4 H2O和[Cu（DOTAM）]（ClO 4）2·H2O。一系列[M（DOTAM）]2+（M = Mn，Co，Cu，Ni，Ca，Zn）配合物的固态和溶液红外光谱特征与固态和溶液配位数有关。[Co（DOTAM）]2+、[Ni（DOTAM）]2+和[Zn（DOTAM）]2+在固态和溶液中均为六配位，而[Mn（DOTAM）]2+和[Ca（DOTAM）]2+在固态和溶液中均为八配位。[Cu（DOTAM）]2+在溶液中的配位数增加到六配位，通过X射线晶体学分析，[Cu（DOTAM）] 2+为五配位。
Three new DOTAM (1,4,7,10-tetrakis(acetamido)-1,4,7,10-tetraazacyclododecane) complexes have been synthesized and characterized by X-ray crystallography: [Co(DOTAM)]Cl2·3H2O, [Ni(DOTAM)]Cl2·4H2O, and [Cu(DOTAM)](ClO4)2·H2O. Solid state and solution IR spectroscopic features for a series of [M(DOTAM)]2+complexes (M = Mn, Co, Cu, Ni, Ca, Zn) correlate with solid state and solution coordination numbers. [Co(DOTAM)]2+, [Ni(DOTAM)]2+, and [Zn(DOTAM)]2+are demonstrated to be six-coordinate in both the solid state and in solution, while [Mn(DOTAM)]2+and [Ca(DOTAM)]2+are eight-coordinate in the solid state and remain so in solution. [Cu(DOTAM)]2+, which is five-coordinate by X-ray crystallography, is shown to increase its coordination number in solution to six-coordinate.
