For decades, the design and synthesis of novel met
alorganic frameworks (MOFs) have been a field of
rapid growth in materials chemistry [1, 2] due to their
exceptionally artistic architectures and potential ap
plications, such as magnetic, gas adsorption and sepa
ration, heterogeneous catalysis and luminescence [3–8].
Meanwhile, crystal engineering of supramolecular poly
mers is also becoming popular not only due to the easily
predicted Hbonding supramolecular synthons [9, 10],
but also due to their potential applications as functional
materials. To achieve these kinds of functional materi
als, it is necessary to precisely position the synthons in
the crystal lattice by means of appropriate noncova
lent interactions between molecules. Carboxylic acids
amides are commonly used functional synthons in
crystal engineering because they easily form robust ar
chitectures via O–H
O Hbonding [11, 12]. This ap
proach can introduce new functions into the system of
supramolecular polymers. Thus, continuing efforts
have been devoted to the purpose of designing and
synthesizing novel molecular architectures . In
this paper, we report on the synthesis, crystal structure
and magnetic properties of [Gd(Sfdb)(NO

sulfonyldibenzoic acid), con
