Abstract

Stoichiometry-controlled complexation of o-phenylenebis-(N,N′-dimethyl-N,N′-ethylene)guanidine (BG) and benzoic acid (BA), which is forming 1 : 1, 1 : 2, 1 : 3, and 1 : 4 BG+BA systems, was observed in solution by using cold-spray ionization mass spectrometry CSI-MS and pulsed field gradient PFG NMR diffusion and in the solid state by X-ray structure analysis.
