Abstract

Four new coordination polymers, namely [Co₃(4,4′-bpy)₄(pa)₄](NO₃)₂(4,4′-bpy)(H₂O)_3.5 (1), [Co(4,4′-bpy)(pa)₂(H₂O)₂](paH)₂ (2), [Zn₃(4,4′-bpy)₄(pa)₄](NO₃)₂(paH)(H₂O)_2.5 (3), [Cu(4,4′-bpy)_0.5(ba)₂] (4), as well as one known compound [Cu(pyz)_0.5(ba)₂] (5) (4,4′-bpy=4,4′-bipyridine; paH=phenylacetic acid; baH=benzoic acid; pyz=pyrazine) have been hydrothermally prepared via metal ion-dependent in situ metal-ligand redox reactions of 2-phenyl-malonic acid (2-phmalH₂). Among them, 1, 2 and 3 contain paH and pa as the decarboxylated products of 2-phmalH₂, while 4 and 5 contain the redox product baH instead of paH. This results show that the decarboxylation occurs easily to 2-phmalH₂ under hydrothermal condition, while an in situ metal/ligand redox reaction undergoes in the presence of copper(II) ion. Compound 1 bearing well isolated, carboxylate-bridged linear trimeric Co₃^II subunits shows intracluster antiferromagnetic interaction (J=-9 K) and no long-range magnetic ordering down to 2 K.
