Inorganic-organic hybrid materials have become an emerging class of new materials with potential for a variety of applications including catalysis, separations, and gas storage etc.. Much of the attraction of these compounds lies in their ability to merge properties of classical solid state inorganic materials with the functionality of organic molecules. Here, we report three new hybrid materials based on 4-cyclohexene-1,2-dicarboxylate (1,2Cy). To date, only the structures of the parent acid, several alkali salts, and a cobalt coordination polymer have been reported, all for the –cis isomer. Three cobalt& maganese compound consist of 0D isolated Co(II) octahedra connected into 1D chains by the difunctional carboxylate, 1D ribbons of corner-sharing MnO6 octahedra, and 2D Mn-O-Mn network with corner- and edge sharing MnO6 octahedra, respectively. Extensive hydrogen bonding appears to occur between the chains and lattice water molecules. We show that under hydrothermal conditions, the 1,2Cy ligand is well-suited to the preparation of lamellar hybrid systems. Moreover, a variety of possible metal-oxygen-metal topologies are possible within the layers. The degree of connectivity between metal centers is significant in influencing the thermal stability and magnetic ordering in hybrid systems. |
