Abstract
The reaction of R3In (R = methyl, tert-butyl, xylyl) with bis(tricyclohexyltin) sulfide, 2-methylpropane-2-thiol, 4,6-dimethyl-2-mercaptopyrimidine, cyclopentanethiol, cyclohexanethiol, 2,5-dimethylbenzenethiol, or 2,6-methylbenzenethiol has yielded seven new indium−sulfur complexes: {m-Xyl2In[μ-SSn(C6H11)3]}2 (2), [t-Bu2In(μ-S-C5H9)]2 (3), [t-Bu2In(μ-S-C6H11)]2 (4), {t-Bu2In[μ-S(2,5-Me2)C6H3]}2 (5), [Me2In(μ-S-t-Bu)]3 (6), {t-Bu2In[μ-S(4,6-Me2)C4N2H]}3 (7), and {Me2In[μ-S(2,6-Me2)C6H3]}4 (8). These complexes have been studied by 1H and 13C NMR spectroscopy, and their structures have been determined by single-crystal X-ray diffraction techniques. 2−5 form dimeric species with planar (In−S)2 cores, 6 forms a trimer which adopts a skew-boat conformation, 7 forms a trimer with a planar six-membered (InS)3 ring with a secondary In−N interaction, giving rise to a pseudo-five-coordinate In atom, and 8 forms a tetramer in an extended chair conformation, the first known indium tetramer. Several of the factors of...
