Abstract

The complexing ability of the binary system trans-aconitic acid (H 3L) with regard to Cd(II) and the crystal structures of the binary system Cd(II)–(H 3L), [Cd 3L 2(H 2O) 6] n( 1) and ternary systems of Cd(II)–(H 3L)–Lewis base [Lewis base = 1,10-phenanthroline ( 2) and 2,2′-bipyridine ( 3)] have been determined. Compound 1 is a rare binodal four-connected three-dimensional (3D) metal-organic framework possessing a moganite ( mog) topology. Compounds 2 and 3 represent infinite one-dimensional (1D) chains forming three-dimensional metal-supramolecular structures through H-bond and π–π stacking interactions. All compounds have been characterized by spectroscopic and thermogravimetric techniques.
