采用阳离子模板法制备了非手性（10,3）网状三维金属-草酸骨架[Cu(2)(C(2)O(4))(3)(2-)](n)。在165 K左右，通道中的阳离子(C(2)H(5))(3)NH（+）的无序跃迁导致介电跃迁，并且在165 K以下通过草化桥的Jahn-Teller扭曲Cu（ii）之间的反铁磁相互作用增强。
An achiral (10,3) net three-dimensional metal-oxalato framework [Cu(2)(C(2)O(4))(3)(2-)](n) was formed by cation-templating. At around 165 K, the disorder-order transition of cation (C(2)H(5))(3)NH(+) 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.
