Crystal structure of a sodium complex, bis-[NN′-ethylenebis(salicylideneiminato)copper(II)]perchloratosodium–p-xylene

摘要: A purple compound is formed between sodium perchlorate and two molecules of the copper complex Schiff's base NN′-ethylenebis(salicylideneimine)(salen); p-xylene solvate has been subjected to three-dimensional X-ray crystal structure analysis. The was solved by Patterson Fourier methods refined full-matrix least squares R 0·070 for 1083 diffractometer observations.
