Abstract

An achiral (10,3) net three-dimensional metal-oxalato framework [Cu₂(C₂O₄)₃²⁻]_n was formed by cation-templating. At around 165 K, the disorder–order transition of cation (C₂H₅)₃NH⁺ hosted in the channel resulted in dielectric transition, and the antiferromagnetic interactions between the Jahn–Teller distorted Cu(II) through the oxalato-bridge below 165 K was enhanced.
