- Abstract
Four novel coordination polymers based on 1,4-diazabicyclo[2.2.2]octane N,N′-dioxide (odabco) with the following formulas [Zn(H2O)2(HCOO)2]·odabco (1), [Zn2(OH)(odabco)2(HCOO)2](NO3) (2), [Zn(odabco) (OAc)2] (3, OAc– = acetate) and [Zn2(odabco)3(OAc)2](NO3)2 (4) are prepared in solvothermal conditions. The structure of these compounds is determined by single crystal X-ray diffraction. The coordination polymer 1 is formate containing odabco guest molecules. The coordination polymers 2-4 contain odabco as a bridging ligand with additional terminally coordinated carboxylate anions. The system of hydrogen bonds in the layered formates 1 and 2 leads to the formation of 3D supramolecular frameworks. The acetates 3 and 4 containing no strong hydrogen bonds are one-dimensional and layered coordination polymers, respectively. It is established that the nature of the carboxylate anion has a decisive effect on the structure of resulting products.
