What is Synthesis, structure, and magnetic properties of two 1-D helical coordination polymeric Cu(II) complexes about?
Two helical coordination polymeric copper(II) complexes bearing amino acid Schiff bases HL or HL 0 , which are condensed from 2hydroxy-1-naphthaldehyde with 2-aminobenzoic acid or L-valine, respectively, have been prepared and characterised by X-ray crystallography. In [CuL] n (1) the copper(II) atoms are bridged by syn-anti carboxylate groups giving infinite 1-D right-handed helical chains which are further connected by weak C-HÁ Á ÁCu interactions to build a 2-D network. While in [CuL 0 ] n (2) the carboxylate group acts as a rare monatomic bridge to connect the adjacent copper(II) atoms leading to the formation of a left-handed helical chain. Magnetic susceptibility measurements indicate that 1 exhibits weak ferromagnetic interactions whereas an antiferromagnetic coupling is established for 2. The magnetic behavior can be satisfactorily explained on the basis of the structural data.
