Strong Antiferromagnetic Interaction

Three coordination polymers having ladder-like topologies owing to the novel bridging modes of [Cr(C2O4)3]3− or Cr2O72− show a strong antiferromagnetic interaction between copper(ii) ions through the oxalate bridge.

Strong Antiferromagnetic Interaction

The X-ray structure, porous and magnetic property of a self-assembled network 1 is described in detail. The single crystal X-ray analysis provides 1 as a three-dimensional network, which contains two-dimensional permanent ring forming nanoscale one-dimensional channels. The inter-replacement of perchlorate and hexafluorophosphate anions in solid 1 proves its porous structure. There is somewhat strong antiferromagnetic interaction (J = −74.1 cm−1) between two copper(II) ions through oxalate bridge and weak antiferromagnetic interaction (J = −5.1 cm−1) through AEP ligand.
