Structural variations in the complexes of cadmium(II), hexamethylenetetramine, and 2-, 3- and 4-nitrobenzoates

Syntheses and structural characterization of four new cadmium(II)-)-hexamethylenetetramine (hmt) complexes with isomeric nitrobenzoates reveal that noncovalent interactions play a very important role in determining the final molecular structures of the self-assembled species.
