| Abstract: | Three cobalt(II) coordination polymers, [Co2(tatb)2(2,2′‐bipy)2 (H2O)2 · DMA · 2H2O] ( 1 ), [Co2(tatb)2(1,10‐phen)2(H2O)2 · 2H2O] ( 2 ) and [Co(tatb)(1,3‐dpp) · H2O] ( 3 ) (H3tatb = 4,4′,4′′‐(1,3,5‐triazine‐2,4,6‐triyl)tribenzoic acid; 2,2′‐bipy = 2,2′‐bipyridyl; 1,10‐phen = 1,10‐phenanthroline; 1,3‐dpp = 1,3‐bis(pyridin‐4‐yl)propane), were synthesized solvothermally and characterized by single‐crystal and powder X‐ray diffraction (PXRD), as well as IR spectroscopy. Complexes 1 and 2 exhibit 1D double‐chain structures, which further connect into interesting 3D networks by hydrogen bond and strong π–π interactions. Complex 3 possesses 2D 44‐sql topology, which is packed parallel in an AA fashion. Moreover, thermal stability properties and photoluminescence properties of 1 , 2 and 3 were also investigated. |
