Reaction of Cu(ClO4)(2). 6H(2)O with 1-methylbenzotriazole (Mebta) in EtOH yields [Cu(Mebta)(4)(H2O)] (ClO4)(2). 0.4EtOH in ca. 75% yield. The structure of this salt has been determined by single-crystal X-ray crystallography. Mebta behaves as a monodentate ligand binding through N(3). The metal coordination geometry is best described as distorted square pyramidal with the H2O ligand occupying the apical site. The complex was also characterized by molar conductivity, room-temperature effective magnetic moment and spectroscopic (i.r., far-i.r., u.v./vis, e.s.r.) studies. The data are discussed in terms of the nature of bonding and known structure. Comparison between the structural and spectroscopic properties of [Cu(Mebta)(4)(H2O)](ClO4)(2). 0.4EtOH and those of the (CuI)-I-I site of Cu-Zn superoxide dismutase shows that the former can be considered as a fairly good model for the latter.
