Two Chiral Coordination Polymers: Preparation and X-ray Structures of Mono(4-sulfo-<scp>l</scp>-phenylalanine)(diaqua) Zinc(II) and Copper(II) Complexes

Abstract

Hydrothermal treatment of 4-sulfo-l-phenylalanine (H2SPA) with Zn(OH)2 and Cu(OH)2 affords two novel 1-D chiral coordination polymers [Zn(SPA)(H2O)2]n (1) and [Cu(SPA)(H2O)2]n (2) as chiral supramolecular aggregates through strong hydrogen bonding of the sulfonate group. 1 also displays a strong second harmonic generation (SHG) response.
