Synthesis and X-Ray Diffraction studies on Some Copper(II) Complexes of Naphthalene Analogues of 2'-Hydroxychalocones

Abstract

Some copper(lI) complexes of naphthalene analogues of  2'-hydroxychalcones
have been synthesised and characterised. The copper(ll) complexes
have the general formula CuL₂. where L is the deprotonated ligand.
the naphthyl chalcone. In the present investigation,  the lattice constants of
the copper(ll) complexes have been determined with the help of X-ray
powder diffraction data. They all have the tetragonal unit cell. On the basis
of cell parameters it has been concluded that (i) replacement of a phenyl
ring by a naphthyl ring results in decrease of cell parameters, and (ii)
ortho substituent tends to increase cell parameters.
