constructed using a triple‐decker PtII complex [Pt3(μ3‐pydt)2(bpy)3]2+ (H2pydt=2,6‐pyridinedithiol, bpy=2,2′‐bipyridine). The divalent complex undergoes electrochemically quasi‐reversible two‐electron transfer coupled with the coordination/dissociation of axial ligands, forming higher valentPt(+2.67) species [Pt3X2(μ3‐pydt)2(bpy)3]2+ (X=Cl−, Br−, and SCN−). These higher valent species exhibit characteristic

comparison of its conformational behaviour with that of related [3.3]metacyclophanes has led to the conclusion that, in addition to steric hindrance effects, conjugative factors may prove important in affecting the syn–anti isomerization of heteroheterophanes .
Synthesis of Paramagnetic Tetranuclear Rhodium and Iridium Complexes with the 2,6-Pyridinedithiolate Ligand. Redox-Induced Degradation to Diamagnetic Triiridium Compounds

Both 2,6-pyridinedithiolate tridentate ligands bridge two metal-metal bonded d(7) centers in pseudo octahedral environments and one d(8) square-planar iridiumcenter. An interpretation of the EPR spectra of the 63-electron mixed-valence paramagnetic tetranuclear complexes suggests that the unpaired electron is delocalized over two

show no evidence for conformational flipping A ∡ B at normal temperatures as a result of steric hindrance (non-bonded interactions) by the internal substituents. A comparison between the inversion barriers of the Me containing compounds 2a and those of the analogous OMe compounds 2b shows that the stericrequirement of OMe groups, which are bonded to the aromatic ring, is considerably greater than those
