The reaction of isophthaloylbis(N,N-diethylthiourea), H2L1, with FeCl3¡¤6H2O gives the dinuclear tris-complex [Fe2(L1)3] (5), possessing a cryptand-like structure. A similar reaction with the ligand 2,6-dipicolinoylbis(N,N-diethylthiourea), H2L2, however, gave the anionic, mononuclear Fe(III) complex [Fe(L2)2]– (6), which could be isolated as its Tl+ salt by the subsequent addition of Tl(NO3). A tighter view to the solid state structure of the obtained product, however, characterizes compound 6 as a 1-dimensional coordination polymer, in which four-coordinate Tl+ ions connect the {[Fe(L2)2]–} units to infinite chains. When Fe3+ ions and Tl+ ions are added to H2L2 simultaneously in a 1-pot reaction, a different product was obtained: a cationic trinuclear complex {M?[Fe2(L2)3]}+. It was isolated as a PF6– salt and represents a {2}-metallacryptate with a nine-coordinate Tl+ ion in the central void. Structurally related products {M?[Fe2(L2)3]}(PF6) (M = Na+, K+, Rb+) (8 PF6) were isolated from analogous reactions with alk. salts instead of Tl(NO3). {2}-Metallacryptates with larger central voids were synthesized with the ether-spaced aroylbis(N,N-diethylthiourea) H2L3. {M?[Fe2(L3)3]}(PF6) (M = K+, Rb+, Tl+ or Cs+) (9 PF6) were prepared by a similar protocol to those with H2L2 with the simultaneous addition of the metal ions to a solution of H2L3. Due to the larger spacer between the aroylthiourea units, the coordination number of the central M+ ions is 12 by six carbonyl and six ether O atoms. All products were characterized by elemental anal., IR spectroscopy, and x-ray structure anal. Cyclic voltammetric studies were carried out with the three representative complexes [Fe2(L1)3], {K?[Fe2(L2)3]}(PF6), and {K?[Fe2(L3)3]}(PF6). The obtained voltammograms indicate dependence of the redox properties of the oligonuclear systems on the conjugation in the organic backbones of the ligands.
