N-Acylamidophosphinates RC(X)NHP(Y)R2 (NAAP) and their thioanalogues (X,Y= O, S; R = Alk, Ar, CCl3, Het, NR2 2, NR2R3; R = Ar, OAlk, OAr, SAlk, NAlk2, NHAr) contain X, Y donor atoms and amide nitrogen, which are capable of taking in complexation with metal cations. An application of NAAP complexes in supramolecular chemistry has been investigated in the last decades. Developed synthetic methods allow us to obtain N-acylamidophosphinate ligands contained multiple chelating groups or a combination of several essentially various coordinating fragments in the molecule: chelating moiety C(X)NHP(Y) and a macrocycle. The latter ligands are capable of connecting ions simultaneously by the chelating sites, and by the "guest-host" mechanism using the macrocycle. The bibliography includes 104 references.

Keywords: thiophosphoric acids, polyfunctional ligands, intramolecular hydrogen bonds, N-phosphorylated amides, coordination compounds, crown-containing ligands
