Effect of Extensive Conjugation of Coordinated Imine on Nature of Bonding and Structure of Cu(II), Ni(II) and Co(II) Complexes of 2'-Hydroxychalconeimine

Bis(2'-hydroxychalconato)copper(II) reacts with p-monoamines and ethylenediamine to form schiff base complexes of the type ML2 where L is N-R-2'-hydroxychalconeimine (R = H, CH3, Et, n-Pr, n-Bu, CH2-).The Cu(II) complexes are also obtained from the preformed schiff bases by amine-exchange and template reactions and by reaction in situ.Extensive conjugation of C=O in the chalcone complex facilitates the attack of the amines.On the other hand, extensive conjugation of C=N in the imine complex (R = H) does not facilitate the amine exchange.The structure and nature of bonding in the complexes have been established with the help of elemental analyses, thermal studies, magnetic measurements and ligand field and infrared spectra.All the Cu(II) bis-chelates are monomeric and possess trans-square planar structure.The corresponding nickel complexes possess associated pseudooctahedral structure and cobalt complexes tetrahedral configuration.All the ethylenediamine derivatives exhibit cis-square planar geometry.The tendency of these complexes to form pyridine adducts is affected by the nature of R group.IR studies reveal that conjugation is damped in the chalconeimines resulting in a relatively weak ligand field strength.Only νCu-O and νCu-N are affected by the R substituent; νC=N and νPh-C=C remain almost constant.
