Sulfur-bridged (CoPtCoIII)-Pt-III-Co-II trinuclear complex acting as an S-donating complex-ligand
The reaction of fac(S)-[Co(aet)(3)] (aet = H2NCH2CH2S-) with [PtCl2{Co(aet)(2)(en)}](+) gave an S-bridged (CoPtCoIII)-Pt-III-Co-II trinuclear complex, [Pt{Co(aet)(3)}{Co(aet)(2)(en)}](3+), ([1](3+)). The crystal structure of [1]Cl-3 was determined by X-ray crystallography. In [1](3+), the central Pt-II, atom is coordinated by four thiolato S atoms from octahedral C-2-cis(S)-[Co(aet)(2)(en)](+) and mer(S)-[Co(aet)(3)] units in a square-planar geometry, giving a linear-type S-bridged trinuclear structure with a non-bridging thiolato group. Treatment of [1](3+) with linear Au-I produced an S-bridged (Co4PtAuI)-Pt-III-Au-II heptanuclear complex, [Au{Pt[Co(aet)(3)][Co(aet)(2)(en)]}(2)](7+) ([2](7+)), which indicated that [1](3+) acts as a new class of S-donating trinuclear complex-ligand.
