アクア[N-(2,5-ジヒドロキシベンジル)イミノジアセタト]銅(II)錯体の結晶構造
This study reports the crystal structure of the copper(II) complex [Cu(C11H11NO6)(H2O)], in which the Cu(II) center adopts a distorted square-pyramidal coordination geometry. The basal plane is occupied by one coordinated water molecule, two carboxylate oxygen atoms, and one nitrogen atom from the tetradentate ligand, with Cu-O distances ranging from 1.9376 to 1.9541 Å and a Cu-N distance of 1.9929 Å. The apical position is filled by a hydroquinone oxygen donor at a Cu-O distance of 2.3746 Å. Intermolecular hydrogen bonding, involving both hydroquinone hydroxyl groups and the coordinated water molecule as donors, establishes a three-dimensional supramolecular framework.
The delivery route is not clearly identifiable from this paper. For hydrogen intake, inhalation is the most efficient route; inhalation, however, carries explosion risk (empirical LFL of 10%; high-concentration devices are not recommended).
