Can sulfur participate in a hydrogen bond?

  1. Aug 8, 2013 #1
    I googled it and got both answers, "yes" and "no."

    What I mean is: O-H-S, F-H-S, N-H-S, etc.

    Ex.'s of "yes": http://www.ncbi.nlm.nih.gov/pubmed/19089987 http://pubs.rsc.org/en/content/artic.../ce/c0ce00760a[/URL]

    Ex. of "no": [URL]http://www.nature.com/nature/journal.../149218a0.html[/URL]

    Thiols and alcohols have similar molecular structure.
    So there are (weak) hydrogen-bonding between individual thiol groups (R-SH)...

    Often hydrogen bonds are regarded as restricted to just O, F and N. But this is misleading as it's actually a polarity continuum from 0 bond dipole moment (only possible when the two atoms of the bond are identical) to purely ionic bonds (an idealization, but something like CsF is very close). It's also misleading because the electronegativity difference between F and N is greater than that between N and Cl or even N and S.
