Pseudo-tetrahedral geometry in the copper(II) complex of a novel 18-membered tetra-aza-macrocyclic ligand; X-ray crystal and molecular structure
Abstract
Condensation of acetone with bis-(1,4-diaminobutane)copper(II) perchlorate yields a purple product, [(5SR,10RS)-2,4,4,11,11,13-hexamethyl-1,5,10,14-tetra-azacyclo-octadeca-1,13-diene]copper(II) perchlorate, which has an unusual pseudo-tetrahedral geometry about CuII, as indicated by X-ray analysis.
