    abstract = "In our effort to develop new synthetic strategies for the isolation of
new phosphonate frameworks, we exploited the possibility of
simultaneously utilizing benzene-1,3,5-triphosphonic acid (H(6)btp) and
di-2-pyridyl ketone (py(2)CO), which is a major player in the field of
polynuclear metal complexes. This ligand blend in Cu-II chemistry
afforded a 2D framework comprising tetranuclear [Cu-4(II)] secondary
building units. A thorough investigation of the Cu-II/di-2-pyridyl
ketone/benzene-1,3,5-triphosphonic acid reaction system also revealed a
hydrogen-bonded framework. The structure of the latter comprises the
cationic [Cupy(2)C(OH)(2)(2)](2+) complex [py(2)C(OH)(2) is the
hydrate of py(2)CO], the dianion of benzene-1,3,5-triphosphonic acid
(H(4)btp(2-)) and water solvates. The magnetic properties of the
coordination polymer were rationalized on the basis of magnetically
isolated [Cu-4(II)] units dominated by antiferromagnetic interactions."
