Transition-Metal Complexes with Sulfur Ligands. 132.1Electron-Rich Fe and Ru Complexes with [MN2S3] Cores Containing the New Pentadentate Ligand ‘N2H2S3‘2-(= 2,2‘-Bis(2-mercaptophenylamino)diethyl Sulfide(2−))

The use of density functional theory (DFT) and time-dependent DFT (TD-DFT) to study the photochemistry of metal complexes is becoming increasingly important among chemists. Computational methods provide unique information on the electronic nature of excited states and their atomic structure, integrating spectroscopy observations on transient species and excited-state dynamics. In this contribution, we present an overview on photochemically active transition metal complexes investigated by DFT. In particular, we discuss a representative range of systems studied up to now, which include CO- and NO-releasing inorganic and organometallic complexes, haem and haem-like complexes dissociating small diatomic molecules, photoactive anti-cancer Pt and Ru complexes, Ru polypyridyls and diphosphino Pt derivatives.

MoClReacting [Mo(O)2(acac)2] (acac- = acetylacetonate) with the tetradentate thioether-thiol ligand 2,3,8.9-dibenzo-1,4,7,10-tetrathiadecane (dttd-H2) yields cis-[Mo(O)2(dttd)] ; this compound is reduced by PPh3 to give [MoO(dttd)], which is also obtained from [MoCl2(dttd)] and H2O. Depending upon the concentrations of the reactants [4(THF)2], CH3SC6H4SH and H2O , in THF the products [MoO(CH3SC6H4S)2] or [MoCl2(CH3SC6H4S)2] are formed. In the analogous reaction between [MoCl4(THF)2] and the pentadentate ligand 2,3,11,12-dibenzo- 1,4,7,10,13-pentathiatridecane (dpttd-H2) in THF/H2O. [MoO(dpttd)] is obtained exclusively. Due to their poor solubility, the Mo(IV)-oxo complexes show only limited reactivity only; with NO reductive nitrosylation to cis-Mo(NO)2 complexes is observed.
