Abstract
A cobalt diphosphonate Co(H(2)O){C(5)H(5)N-CH(2)CH(OH)(PO(3))(PO(3)H)} (1) has been synthesized under hydrothermal conditions. It shows a novel type of double chain structure in which one of the two CPO(3) terminus caps on top of the {Co(2)(micro-O)2} dimer while the other connects the adjacent {Co(2)(micro-O)2} dimers into a chain. The magnetization measurements reveal that dominant antiferromagnetic interactions are mediated between the magnetic centers and the compound experiences a field-induced magnetic transition at low temperature with H(c) of ca. 15 kOe at 1.8 K.
