A novel one-dimensional acentric copper(I) coordination polymer with second-harmonic generation response

The reaction of N,N-(2-pyridyl)(4-pyridylmethyl)amine with [Cu(MeCN)2(PPh3)2]ClO4 in the presence of THF affords a novel one-dimensional copper(I) coordination polymer {[Cu(PPh3)(N,N-(2-pyridyl)(4-pyridylmethyl)amine)](ClO4)}n (1), which crystallizes in an noncentrosymmetric space group and displays strong second-harmonic generation (SHG) response.
