Structure, magnetic and ion-exchange properties of self-assembled triaza-copper(II)-oxalate hybrides having nanoscale one-dimensional channel.

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.
