A novel (μ-OAc)2 bridged unsymmetric coordinated binuclear Mn(II) macrocyclic complex with ligating pendant-arm

The Mn(II) dinuclear complex with an uncoordinating cavity was obtained by (2+2) condensition reaction between dialdehyde and branched polymine. The complex shows weakly antiferromagnetical coupling between two Mn(II) ions and the CAT-like activity.
