Abstract
ESR spectra show-the simultaneous presence of a planar trans and a nea rly planar cis isomers in the 1:2 ratio for all ''S, O'' compounds Cu( R1R2N-CS-N-COR)(2) whereas an only isomer is present with the analogou s ''S, N'' compounds. A strong tetrahedral distortion is observed when a bulky substituent is present on the nitrogen donor atom. (C) 1998 E lsevier Science Ltd. All rights reserved.
