Abstract: Twelve new coordination polymers have been obtained using three different azodibenzoate ligands, 3,3′'-azodibenzoic acid (3,3′'-ADB), 3,3′'-azoxydibenzoic acid (3,3′'-AODB) and 4,4′'-azodibenzoic acid (4,4′'-ADB) in combination with a variety of metal ions and co-ligands. Their crystal structures have been elucidated using single crystal X-ray diffraction analysis and the thermal stabilities of some of the products have been investigated using thermogravimetric analysis. The compounds, [Pb(3,3′'-ADB)(phen)] n (1), [Cu 2(3,3′'-AODB) (PPh 3) 2] n (2), [Zn(4,4′'-ADB)(Py) 2] n (3), [Cd(4,4′'-ADB)(H 2O) 2] n (4), and [Co(4,4′'-ADB)(Py) 2(H 2O) 2] n (5), form 1-D chains. Compounds Zn(3,3′'-ADB)(CH 3CH 2OH) (6) and Co 3(3,3′'-ADB) 2(phen) 2(CH 3COO) 2 (7) form 2D sheets which have the (4,4) topology. Two-dimensional sheets are also formed in the case of Cd(4,4′'-ADB)(phen) (H 2O) (8), Y 2(3,3′'-ADB) 3(phen) 2 (9), Sm 2(3,3′'-ADB) 3(phen) 2 (10) and Er 2(3,3′'-ADB) 3(phen) 2 (11) with 9, 10 and 11 being isomorphous. In the structure of Ba(4,4′'-ADB) (12), Ba(ii) carboxylate units form 2D sheets which are linked by organic links to form a 3D pillared structure.
