•Reaction of CdSO4 with tpcb and 5-R-1,3-H2BDC (R = H, NO2) gave two complexes.•1 has a 3D (4,4)-connected net with a (66)2(64 · 82) Schläfli symbol.•2 has a 3D (3,4,5)-connected net with a (52 · 8)(54 · 6 · 8)(4 · 53 · 62 · 7 · 82 · 10) topology.•It offers insight into how the MOF arrays are affected by substituent groups.
Hydrothermal reactions of CdSO4 with tetrakis(4-pyridyl)cyclobutane (tpcb) and 1,3-benzenedicarboxylic acid (1,3-H2BDC) or 5-nitro-1,3-benzenedicarboxylic acid (5-NO2-1,3-H2BDC) resulted in the formation of two coordination polymers [Cd(tpcb)0.5(1,3-BDC)]n (1) and {[Cd2(tpcb)(5-NO2-1,3-BDC)2(OH2)2] · 4H2O}n (2), respectively. Compounds 1 and 2 were characterized by elemental analysis, IR, powder X-ray diffraction, and single-crystal X-ray diffraction. 1 and 2 exhibit two different types of two-fold interpenetrating 3D architectures with (66)2(64 · 82) and (52 · 8)(54 · 6∙8)(4 · 53 · 62 · 7 · 82 · 10) Schläfli symbols, respectively. Their thermal and photoluminescent properties were also investigated.
Graphical abstractTwo Cd(II) 3D coordination polymers [Cd(tpcb)0.5(1,3-BDC)]n and {[Cd2(tpcb)(5-NO2-1,3-BDC)2(OH2)2] · 4H2O}n were generated from hydrothermal reactions of CdSO4 with tetrakis(4-pyridyl)cyclobutane (tpcb) and 1,3-benzenedicarboxylic acid (1,3-H2BDC) or 5-nitro-1,3-benzenedicarboxylic acid (5-NO2-1,3-H2BDC). These complexes were structurally characterized by elemental analysis, IR, and X-ray crystallography and their thermal and luminescent properties were studied.Figure optionsDownload full-size imageDownload as PowerPoint slide
