Abstract
The complex [RhIII(pyS)3(pySH)], containing two chelating pyridine-2-thionato (pyS) ligands, one monodentate S-bonded pyridine-2-thionato ligand, and one monodentate S-bonded 1H-pyridine-2-thione (pySH) ligand, reacts with triethylamine and two equivalents of the 2-methylallyl complex [Pd(η3-C4H7)S2][BF4](S = solvent = H2O or acetone) to yield the trinuclear compound [RhIII(pyS)2(µ3-pyS)2{PdII(η3-C4H7)}2][BF4], (1). The structure of (1), determined by single-crystal X-ray diffraction, contains two chelating pyridine-2-thionato ligands at rhodium and two which bridge all three metal atoms as part of a bicyclic cage. None of the metal atoms is within bonding distance. The structure may be regarded as containing the cyclic bidentate ligand [Pd2(µ-pyS)2(η3-C4H7)2] chelated to the group [RhIII(pyS)2]+ through two sulphur atoms.Keywords
