An Unusual Open-framework Cobalt(II) Phosphate with a Channel Structure That Exhibits Structural and Magnetic Transitions
Magnetic and structural transitions at low temperatures are exhibited by the novel open-framework cobalt(II) phosphate of the composition [enH2][Co3.5(PO4)3] (en=ethylenediamine), the structure of which contains 12-membered channels (see picture). in the presence of a magnetic field, the compound undergoes a transition between two ferrimagnetic states.
