Solid–vapor reaction properties of copper(II) and cadmium(II) sulfonates with amines

The solid–vapor reaction properties of three transition metal sulfonates and amines were investigated and the reaction products were characterized by EA, TGA, IR, PXRD and single crystal structure analyses. [Cu(1,5-nds)(H2O)4]n (I), [Cu(H2O)6](1,5-nds) (II) (1,5-nds = 1,5-naphthalenedisulfonate) and [Cd(p-NH2C6H4SO3)2] (III) can react with primary alkyl amine vapors and form stable monoamine-coordinated Cu(II) and Cd(II) complexes. All of the amine adducts are crystalline materials. The reactions between [Cd(p-NH2C6H4SO3)2] (III) and C2H5NH2 or n-C3H7NH2 produced single crystals in situ via the solid–vapor reaction process.
