Solvothermal Synthesis of the Canted Antiferromagnet {K2[CoO3PCH2N(CH2CO2)2]}6⋅x H2O

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.
