چکیده
|
Irreversible solid-state conversion of co(ii) metal–organic nanocapsule [co2(bda)2(bpy)2] (1), [bda2− = 2,2′-biphenyl dicarboxylate and bpy = 2,2′-bipyridine], prepared by mechanochemical procedure with empty pore and lozenge-shaped microcube morphology similar to [cu2(bda)2(bpy)2]∙4h2o (2) analogue with agglomerated nanostructure morphology was studied. the structure of 1 is exactly the same as 2 and the metal ion has distorted octahedral coordination in both of them. in addition to the same structures of 1 and 2, the similar crystal data of them also approved that this reaction can occur in solid state by cation exchange process. solid-state cation exchange processes of these metal–organic nanocapsules were studied by ir spectroscopy, x-ray powder diffraction (xrd) and scanning electron microscopy (sem).
