标题化合物[(mtan)Zn(OH2)](ClO4)2 (1) (mtan = 5-甲基-1,5,9-三氮杂壬烷) 是在pH < 7 的乙腈水溶液中制取的,而在11 > pH 7的条件下,配合物1中的水分子配体很容易电离出质子,形成二聚体[(mtan)Zn(m-OH)Zn(mtan)](ClO4)3 (2)的产率很高。在13.5 > pH 11的范围内,溶液中就会产生 [(mtan)Zn(m-O)Zn(mtan)](ClO4)2 (3),X-射线单晶结构分析表明,化合物(2)由[(mtan)Zn(m-OH)Zn(mtan)]3+和三个ClO4-组成,晶体参数:单斜晶系空间群P2(1)/m,a轴 7.802(2), b轴 12.121(3),c轴 15.662(3) 牛琤 104.29(2)o,V 1435.3(6) 3。Zn(II)呈现稍微扭曲的四面体配位环境。
The title compound [(mtan) Zn (OH2)] (ClO4) 2 (1) (mtan = 5-methyl- 1,5,9-triazonane) is prepared in aqueous acetonitrile at pH <7 , And at 11> pH 7, the water ligands in complex 1 easily ionize out of protons to form dimers [(mtan) Zn (m-OH) Zn (mtan)] (ClO4) 3 2) high yield. The structure of [(mtan) Zn (mO) Zn (mtan)] (ClO4) 2 (3) was observed in the range of 13.5> pH 11. (mtan) Zn (mtan)] 3+ and three ClO4- crystals. The crystal parameters are: monoclinic space group P2 (1) / m, a axis 7.802 (2), b axis 12.121 ( 3), c-axis 15.662 (3) Beef 琤 104.29 (2) o, V 1435.3 (6) 3. Zn (II) presents a slightly distorted tetrahedral coordination environment.
