Hydrothermal synthesis, crystal structure and third-order non-linear optical property of a novel one-dimensional copper(I) cyanide–organodiimine coordination polymer [Cu 6(CN) 6(phen) 4] n (phen=1,10-phenanthroline)

Abstract

A novel one-dimensional chain coordination polymer [Cu 6(CN) 6(phen) 4] n 1 was synthesized from the simple hydrothermal reaction of Cu(CH 3COO) 2·H 2O, K 3[Fe(CN) 6] and phen·H 2O. With phen, CuCN exhibits a novel B–C–B–C chain array, namely the infinite chain is propagated via alternately three-coordinate (B) and four-coordinate (C) sites of monovalent Cu ions. It should also be noticed that the compound is the first example where the parent chain not only exhibits the [Cu(phen)] + side arm, but also is directly bound to the chelate ligand. Moreover, the third-order non-linear optical property of compound 1 was also investigated and it shows the reverse saturable absorption and self-focusing performance.
