A new tetradentate mixed aza-thioether macrocyclic ligand 2,6-dithia[7](2,9)-1,10-phenanthrolinophane ([13]ane(phenN2)S2) was successfully synthesized. Reacting metal precursors [Fe(CH3CN)2(OTf)2], Ni(ClO4)2·6H2O, and Cu(ClO4)2·6H2O with one equivalent of [13]ane(phenN2)S2 afforded [Fe([13]ane(phenN2)S2)(OTf)2] (1), [Ni([13]ane(phenN2)S2)](ClO4)2 (2(ClO4)2), and [Cu([13]ane(phenN2)S2)(OH2)](ClO4)2 (3(ClO4)2), respectively. The structures of [13]ane(phenN2)S2 and all of its metal complexes were investigated by X-ray crystallography. The [13]ane(phenN2)S2 was found to behave as a tetradentate ligand via its donor atoms N and S.

Solvothermal Syntheses

Two thioarsenates [Co(dien)2]3[As3S6]2 (1, dien = diethylenetriamine) and [Mn(teta)]2As2S5 (2, teta = triethylenetetramine) have been solvothermally synthesized and structurally characterized. 1 consists of isolated cyclic [As3S6]3− anions in a chair-conformation and two different isomeric [Co(dien)2]2+ cations, while 2 consists of neutral [Mn(teta)]2As2S5 moieties built up from saddlelike As2S5 anions as a tetradentate ligand connecting two [Mn(teta)]2+ groups via terminal S atoms. The optical absorption spectrum of 1 is described.
