Abstract
A three-dimensional (3D) binodal 3,5-connected net, {[Cu(MTP)(H(2)O)](NO(3))}(n) (1) with the Schläfli symbol of {3·7(2)}{3(2)·7(5)·8(3)} can be transformed into a two-dimensional (2D) kagóme network with the Schlafli symbol of {3(2)·6(2)·7(2)} in an irreversible single crystal-single crystal (SC-SC) guest-assisted linker exchange process. The product of this SC-SC represents the first luminescent probe for S(2-) based on triazole ligand.
