Bond lengths thiolate complexes

Table I compares selected bond lengths for complexes 1, 2, 3, and 4. As was observed by Maroney and coworkers for an octahedral complex containing both Ni-thiolate and Ni-sulfinate groups, the Ni-Ssulfinyl distance of 2.140(1)A is shorter than is the Ni-Sthiolate distance, 2.163(1)A. The latter is essentially the same as in the parent complex 1, 2.159(2) A. The short N1-S02R distance is accounted for by the decrease in radius of S+2 in the sulfinate as compared to S in the thiolate. Table I compares selected bond lengths for complexes 1, 2, 3, and 4.

X-ray absorption spectroscopy is a powerful method to assess the structure of mercury thiolate complexes. X-ray Absorption Near Edge Structure (XANES) spectroscopy can cleanly differentiate Hg(0), Hg(I) and Hg(II) by the energy of the emission edge. Extended X-ray Absorption Fine Structure (EXAFS) spectroscopy provides information regarding the coordination number and Hg-S bond distances. Typically, the EXAFS spectrum can establish the coordination number (/.e., number of sulfur atoms) to within 20%. More important, the bond length precision is 0.01 A. Given that each increase of one... [Pg.190]
