Abstract
The nickel(II) complex of the quadridentate heterocycle hexamethyl-1,4,8,11-tetra-azacyclotetradecadiene [formed by reaction of trisdiaminoethanenickel(II) with acetone] occurs in two non-interconvertible isomeric forms, considered due to cis and trans arrangements of the heterocycle ring components. One of these isomers occurs as two inter-convertible forms, considered to be conformational isomers stabilized by steric hindrance. The perchlorate and tetrachlorozincate salts of the three isomers are described.Keywords
