アクア-(1,4,7,10-テトラアザシクロドデカン)亜鉛(II)ビス(過塩素酸塩)の結晶構造解析
This crystallographic study characterizes a zinc(II) complex incorporating a 12-membered tetraazamacrocyclic ligand and a coordinated water molecule. The zinc center adopts a slightly distorted square-pyramidal geometry, with the water molecule occupying the apical coordination site. Within the crystal lattice, the macrocyclic ring is observed in two conformations of equal occupancy. Among the three perchlorate counterions, two are located on a twofold rotation axis, and one exhibits oxygen atom disorder with occupancies of approximately 0.62 and 0.38. Intermolecular hydrogen bonding involving the perchlorate anions links the complex units throughout the crystal.
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).
