| Abstract: | Summary Chelate complexes having a 1 2 CuII ion:(singly deprotonated ligand ratio, formed from CuII including 2-, 3- and 4-chlorobenzhydrazides, (ClC6H4C(O)NHNH2) have been studied in the pH > 10 region. With the 2-chloro substituted derivative the cis-isomer is formed, whereas with the 3- and 4-chloro substituted derivatives trans-isomers are formed. The complexing schemes are described. |
