Title
Copper(II) bromide/1-methylbenzotriazole chemistry : variation of product as a function of solvent and ligand-to-metal reaction ratio
Author
Abstract
A systematic investigation of the CuBr2/Mebta (Mebta = 1-methylbenzotriazole) reaction system is described. Particular emphasis has been placed on determining the influence of the Mebta:Cu-11 ratio and the nature of solvent on the identity of the reaction products. These combined variations have led to the preparation of the following complexes; [CuBr2(Mebta)](n) (1), [CuBr2(Mebta)(2)(MeCN)]. MeCN (2), [CuBr2(Mebta)(2)] (3) and [CuBr2(Mebta)(3)]. 0.25H(2)O (4). Complexes 2, 3 and 4 have been structurally characterized by single crystal X-ray studies. Mebta behaves as a monodentate ligand binding through N(3). The geometry about copper(n) in 3 is tetrahedrally distorted trans square planar, while complexes 2 and 4 have distorted trigonal bipyramidal stereochemistries. The new complexes were characterized by elemental analyses, magnetic susceptibilities at room temperature and spectroscopic (IR, far-IR, UV/VIS) techniques. A doubly bromo-bridged chain structure with two alternating chromophores is assigned for 1. All data are discussed in terms of the nature of bonding and known or assigned structures. A comparison of the CuBr2/Mebta and CuCl2/Mebta systems is also presented. (C) 1999 Elsevier Science Ltd. All rights reserved.
