A range of complexes of the binucleating tetrathio- and tetraseleno-ether ligands, 1,2,4,5-C6H2(CH2EMe)4 (E = S, L3 or Se, L4) or C(CH2EMe)4 (E = S, L5 or Se, L6) and of bidentate analogues 1,2-C6H2(CH2EMe)2 (E = S, L1 or Se = L2) with molybdenum and tungsten carbonyls and manganese carbonyl chloride have been prepared, and characterised by IR and multinuclear NMR (1H, 13C{1H}, 77Se, 55Mn, 95Mo) spectroscopy and mass spectrometry. Crystal structures are reported for [Mo(CO)4(L2)], [Mo(CO)4(L3)], [Mo(CO)4(μ-L3)Mo(CO)4], [Mo(CO)4(L4)], [Mn(CO)3Cl(μ-L3)Mn(CO)3Cl], [Mo(CO)4(μ-L5)Mo(CO)4], [Mn(CO)3Cl(L5)] and two forms (containing meso and DL diastereoisomers) of [W(CO)4(L5)].
Reversible structural isomerisation in rare thioether complexes of cobalt(ii) - Effects of ligand architecture
Evans, John,Levason, William,Manning, Joanna M.,Reid, Gillian,Tsoureas, Nikolaos,Webster, Michael
, p. 1986 - 1988 (2007)
Rare examples of (high spin) Co(ii) complexes with geometrically constrained tetrathioether ligands exhibit a very unusual structural isomerism, switching reversibly between tetrahedral monomers in solution and octahedral chain polymers in the solid; the crystal structures of one polymeric species and a tetrahedral monomer model compound are described.
