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 II 4 ] 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 [Cu{py 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 II 4 ] units dominated by antiferromagnetic interactions.
