Trigonal bipyramidal geometry, copper complexes

There are several reasons for the extensive use of copper Lewis acids in stereoselective transformations (i) predictable coordination geometry about the metal, (ii) ready availability, (iii) two oxidation states, and (iv) moderate Lewis acidity. Copper(II) complexes usually adopt a square planar, square pyramidal, or trigonal bipyramidal geometry, whereas Cu(I) complexes have a preference for tetrahedral geometry (Figure 1). [Pg.544]

The Near-IR/vis absorption spectrum of complex 73 in water-NaOH solution was fully consistent with a trigonal-bipyramidal geometry of the copper(II) ion and the EPR spectrum is in agreement with a five-coordination sphere with the cation bound to the four nitrogen atoms of the tren unit and to one solvent molecule, a structure similar to that proposed for the parent complex 71 soluble in organic solvents. Thus it appears that the water solubilization retains the geometry of the complex around the metal center, but it was found that the redox properties were... [Pg.553]
