Aminolysis of hexachlorocyclotriphosphazene, N3P3Cl6, by dithiadiamines in suitable conditions yields mono-SPIRO species which constitute new macrocyclic monocyclophosphazenic structures containing sulphur atoms in their loops.Such (S,S) compounds are isologous to previously described oxygenated cyclophosphazenic cages which are commonly capable of inclusion of "hard" metals.Thus, one may expect that (S,S) cages will be useful for inclusion of "soft" metals.The X-ray structure of the (S,S) mono-SPIRO derivative from 3,7-dithianonane-1,9-diamine (coded as SS232) reveals two crystallographically independent molecules in the unit cell, and also shows the conformations of SPIRO loops.

Two series of zinc(II) complexes of two Schiff bases (H2L 1 and H2L2) formulated as [Zn(HL 1/HL2)]ClO4 (1a and 1b) and [Zn(L 1/L2)] (2a and 2b), where H2L1 = 1,8-bis(salicylideneamino)-3,6-dithiaoctane and H2L2 = 1,9-bis(salicylideneamino)-3,7-dithianonane, have been prepared and isolated in pure form by changing the chemical environment. Elemental, spectral, and other physicochemical results characterize the complexes. A single crystal X-ray diffraction study confirms the structure of [Zn(HL1)]ClO4 (1a). In 1a, zinc(II) has a distorted octahedral environment with a ZnO 2N2S2 chromophore.

Some dibenzamide derivatives with a thioether linker were designed, synthesized and characterized. The specific responses to Hg2+ and Fe3+ were investigated by fluorescence. According to fluorescence titration, the Job plot, 1H NMR, and ESI-mass analysis, the derivative with mono-hydroxyl substituent (1b) on the aromatic ring has high selectivity for Fe3+ ion with the formation of 1:1 1b-Fe3+ complexes. The specificity of 1c for Hg2+ could be switched by swapping the substituent from hydroxyl to amino, and a 1:2 (1c-Hg2+) complex was formed. Along with the obtained results, density functional theory (DFT) and natural bond orbital (NBO) analyses, Time-dependent (TD) DFT and natural transition orbital (NTO) analyses were employed to explore the geometric structures, properties and possible mechanisms.

Novel macrocyclic dithiadiamides, promising reagents as selective ligands for platinum-group metals, have been prepared by reaction of substituted malonic acid dichlorides with sulfur-containing diamines in dilute benzene solution.
Complexes of macrocyclic compounds

, (2008/06/13)
Novel macrocyclic (monocyclic and bicyclic) compounds having nitrogen bridgehead atoms and having in the hydrocarbon bridging chains at least two additional hetero atoms selected from the group consisting of sulfur, oxygen, and nitrogen, when admixed with a compatible cation-donor compound form stable cation-containing macrocyclic complexes which, in turn, can be conveniently dissociated by addition of acid or a quaternizing agent. The novel macrocyclics are valuable for use in the same way and for the same purposes as chelating agents.
