Özet
A new thermally highly stable 2D coordination polymer, formulated as [Co(μ6-abtc)0.5(μ-obix)]n (abtc = dioxygenated form of 3,3′,5,5′-azobenzenetetracarboxylate) obtained employing the semi-flexible 1,2-bis(imidazole-1-ylmethyl)benzene (obix) linker in hydro(solvo)thermal method. The complex was characterized by various techniques such as IR spectroscopy, elemental analysis, single crystal and powder crystal analysis. Crystallographic study of complex 1 reveal that two metal(II) ions are linked by O atoms of carboxylate groups of abtc ligand to build paddle-wheel SBU (secondary building unit). These SBUs are stabilized by the connection of obix ligand. The Co(II) ions are µ6-bridged by hexadentate abtc ligand to generate 2D polymer layers with 3,4-connected binodal net (point symbol {4.62}2{42.62.82}) and topological type is 3,4L13. Thermal analysis shows that complex 1 thermally stable up to 401 °C.
