Abstract
Three new Zn(II) complexes based on different organic-carboxylic acids, [Zn(mba) 2 (2,2′-bipy)] ( 1 ), [Zn(mpdaH) 2 (H 2 O) 4 ] · 4H 2 O ( 2 ) and [Zn(cda) 2 (H 2 O) 2 ] n ( 3 ) (Hmba = 4-methylbenzoic acid, H 2 mpda = 2,6-dimethylpyridine-3,5-dicarboxylic acid and H 2 cda = chelidonic acid) have been synthesized successfully under hydrothermal conditions. X-ray single crystal diffractions show that compounds 1 and 2 are the mononuclear and 3 is one-dimensional chain, in which the Zn(II) centers have different coordination geometries with octahedron for 1 and 2 and tetrahedron for 3 . Through π–π stacking and/or hydrogen bonding (O–H⋯O and O–H⋯N) interactions, different supramolecular structures are assembled, namely, 2D supramolecular layer for 1 and 3D supramolecular networks for 2 and 3 . Furthermore, the IR, TGA and luminescent properties are also investigated in this work.
