二聚标题铜(II)配合物[diaqua-1κO，2κO-bis[3，9-dimethyl-6-(2-pyridylmethyl)-4，8-diazaundeca-3，8-diene-2，10-dione(C17H24N5O2)2](−)2](ClO4)2与1：2κ5O2：N2，N4，N8，N10-二氯酸二铜(II)[Cu2(C17H24N5O2)2](ClO4)2在四方锥体环境中结晶，另一个铜原子呈扭曲的八面体配位。在每种情况下，配体核心的四个N原子(两个亚胺和两个肟N原子)形成金字塔的底部，在顶端有一个水分子。二聚体的两个部分通过一个铜原子和一个与第二个铜原子配位的肟O原子之间的相互作用[2.869 (2) ä]连接，也通过第二个铜原子上的顶端水分子和第一个铜原子配位球上的吡啶氮原子之间的氢键连接。套索臂上的吡啶基N原子没有与铜原子配位。因此，这种潜在的五齿配体只有在与CuII配位时才是四齿配体。
The dimeric title copper(II) complex, diaqua-1κO,2κO-bis[3,9-dimethyl-6-(2-pyridylmethyl)-4,8-diazaundeca-3,8-diene-2,10-dione dioximato(1−)]-1k4N2,N4,N8,N10;1:2κ5O2:N2,N4,N8,N10-dicopper(II) diperchlorate, [Cu2(C17H24N5O2)2](ClO4)2, crystallizes with one Cu atom in a square-pyramidal environment and the other Cu atom displaying a distorted octahedral coordination. In each case, the four N atoms in the core of the ligand (two imine and two oxime N atoms) form the base of the pyramid, with a water molecule at an apex. The two parts of the dimer are linked by an interaction [2.869 (2) Å] between one of the Cu atoms and one of the oxime O atoms coordinated to the second Cu atom, and also by a hydrogen bond between the apical water molecule on the second Cu atom and the pyridyl N atom from the coordination sphere of the first Cu atom. The pyridyl N atoms of the lariat arms are not coordinated to either of the Cu atoms. Thus, this potentially pentadentate ligand is only tetradentate when coordinated to CuII.
