Three new metal complexes, [Pb(dppz)(2,4′-bpdc)] n · n (H 2 O) ( 1 ), [Fe(dppz)(2,4′-bpdc)(H 2 O)] n ( 2 ) and [Cu(dppz)(2,4′-bpdc)(H 2 O)] n ( 3 ) (2,4′-H 2 bpdc = 2,4′-biphenyldicarboxylic acid and dppz = dipyrido[3,2- a :2′,3′- c ]phenazine), have been synthesized and characterized by elemental analysis, IR, X-ray single-crystal diffraction and powder X-ray diffraction. The complexes 1 , 2 and 3 have 1D chains formed via coordination bonds, and unique three-dimensional or two-dimensional supramolecular structures are further formed due to π–π stacking interactions. The results reveal that the coordination preferences of metal ions play a critical role in the framework construction of these complexes. Meanwhile, the thermogravimetric analysis and photoluminescent property of compounds 1–3 have also been investigated.
