“…A novel 3-D manganese open-framework, [NH 3 (CH 2 ) 2 NH 3 ][MnP 2 O 7 ] has been synthesized under ionothermal conditions and characterized by single crystal X-ray diffraction [26]. The bridged binuclear complex, [Co 2 (phendione) 4 (P 2 O 7 )]•nH 2 O was prepared, structurally and magnetically characterized [27].…”
