Linear to spiral coordination polymers of 1,4-naphthalene di-(2-oxyacetate) of cobalt, manganese and copper

► Varieties in structural features of coordination complex and polymers of flexible carboxylic acid are shown. ► Example of aqua bridged cobalt binuclear units acting as node to form tetranuclear complex is shown. ► A manganese dicarboxylate coordination polymer with one carboxylate end bridging is demonstrated. ► Square pyramid geometry around copper (II) ions guide formation of spiral coordination polymer.
