Solvothermal Synthesis of the Canted Antiferromagnet {K2 [CoO3 PCH2 N(CH2 CO2 )2 ]}6 ⋠x H2 O.

A rare example of a molecular species prepared by solvothermal synthesis is the macrocyclic cobalt phosphonate/carboxylate 1, whose structure is shown schematically. At low temperatures this compound displays spontaneous magnetization due to canted antiferromagnetic ordering, which is very unusual for a discrete molecular material.
