摘要

The AFM method has been used for research of possibility of the stable supramolecular nanostructures formation based on Ni(Fe)ARD Dioxygenases models: iron complexes Fe_x~(III)(acac)_y18C6_m(H2O)_n, and nickel complexes Ni_xL)y~1(L_(ox)~1)_z(L~2)_n(H2O)_m, {Ni~(II)(acac)2·L~2·PhOH} (L~2 = MP, HMPA, MSt(M = Na, Li)), triple system {Ni~(II)(acac)2 +Tyr + PhOH} (Tyr=L-Tyrosine) - with the assistance of intermolecular H-bonds. Role of Ni(Fe)- macrostructures in mechanisms of catalysis is discussed.
