A comparison of the coordination of two linkage isomers of bis(1-methylthioimidazolyl)methane to zinc salts

A structural comparison of the coordination chemistry of the two linkage isomeric forms of bis(1-methylthioimidazolyl)methane, [H2C(N-mt)(2)] (L-S), and [H2C(S-mt)(2)] (L-N) to a number of zinc complexes has been carried out. The complexes ZnX2LS and ZnX2LN (where X = Cl, Br and I) have all been prepared in good to high yields and have been characterised by spectroscopic and analytical methods. X-ray crystallography studies were also carried out on all of the newly prepared compounds, revealing kappa(2)-SS and kappa(2)-NN coordination modes for L-S and L-N containing complexes, respectively.
