## Abstract The temperature and concentration dependence of the ^1^H NMR spectra of four anilinomethylenemalonic acid derivatives were determined in CDCl~3~ and DMSO‐__d__~6~ to assign the __E__–__Z__ isomers and to investigate the formation of intra‐ and intermolecular hydrogen bonds. Chemical shi

✦ Synopsis
1H and 15N NMR chemical shifts of 12 semicyclic amidinium salts are reported. Their E/Z equilibria in solution were analyzed by 1D and 2D 1H and 15N NMR techniques. In the solid state the Z-conÐguration is observed.
