Abstract
The reactions of 5-(4-pyridyl)-1,3,4-oxadiazole-2-thiol (Hpyt) with typical octahedral metal ions (Co II and Ni II ) under different conditions generate a series of porous coordination polymers with the general formula of {[M(pyt) 2 (H 2 O) 2 ] · (solvents)} n . In all these complexes, the versatile pyt anionic ligand behaves as the thioamide isomer with the μ- N py , N oxa binding fashion, as confirmed by the X-ray crystallographic studies. Generally, the pyt linkers connect the metal centers to afford uniform 2-D grid-like host coordination frameworks, which stack in a parallel manner to engender the final 3-D crystalline lattices with 1-D open channels. Especially for Co II , different reactive routes and media lead to the productions of four analogous compounds with the inclusion of varied guest solvates, in one of which unusual water clusters are observed.
