Four copper(II) complexes of N , N '-bis(4-methoxysalicylidene)-1,2-diimino ethanemonohydrate ( 1 ), N , N '-bis(5-methoxysalicylidene)-1,2-diiminoethane ( 2 ), N , N '-bis(3-methoxysalicylidene)-2,2-dimethyl-1,3-diiminopropane ( 3 ) and N , N '-bis(4-methoxysalicylidene)-2,2-dimethyl-1,3-diiminopropane ( 4 ) have been prepared and characterized spectroscopically. The solid-state structures of the complexes were established by X-ray crystallography. Complexes 2 , 3 and 4 contain Cu(II) in a tetrahedrally distorted square planar environment with two phenolate O atoms being deprotonated. Complex 1 is five-coordinate and displays color isomerism.
