Description	Amidinium groups combine hydrogen bonds and electrostatic interaction to bind anions. Their complementarity to oxo-anions such as carboxylates, phosphates and sulfates is well known. Simple amidinium-carboxylates X-C(=NH)NH2HO(O=C)C-Y, where X = H, CH3,OCH3, NHCH3, SCH3, C6H5, subst. phenyl; Y = H, CH3, CF3, COCH3, C6H5, subst. phenyl, were synthesized in our laboratory. The substitution effect transfer between amidinium and carboxylate part of the molecule via hydrogen bonds has been proven. Owing to partially covalent character of this interaction and suitable physico-chemical properties including good solubility with negligible dissociation in aprotic solvents, these structures may be of great importance when forming macrocyclic complexes. Bifunct ional cyclic amidinium carboxylates (alkanediyl-, arenediyl- or heteroarenediyl-) as interesting molecules in the field of supramolecular chemistry are target compounds in the present work.
