“…Certain aspects of the coordination chemistry of the methylmercury cation which are relevant to the results described in this paper have been investigated previously. Waugh, Walton, and Caswick determined KL to be 3.23 X 109 by poten tiometric titration (9). However, Schwarzenbach and Schellenberg found it necessary in similar studies to consider the formation of the polynuclear complex (CH3Hg)2OH+ at intermediate pH's; they determined Ki to be 2.34 X 10s and K2 to be 2.34 X 102 (2).…”

“…[CH3Hg+]2 + V + 9^) [CHsH8+] -[CH3Hg]( = 0 (9) The concentrations of the other methyl-mercury species were then calculated using Equations 3 and 5. From these concentrations and a starting value for <5( 3 8)2 equal to the chemical shift at the pH where the calculations using the reported values for Kx and K2 indicated the largest fraction of (CH3Hg)2-OH+ to be present, a predicted chemical shift was calculated using Equation 6.…”

“…13 C, 31 P, and 29 Si CP/MAS (cross-polarization/magic angle spinning) as well as 13 C CP-MAS-DD (cross-polarization/magic angle spinning/dipolar dephasing; dephasing time τ = 45 μs) solid-phase NMR spectra were obtained on a Chemagnetics Inc. 25.1 MHz M-100 spectrometer . Elemental analyses were done by Guelph Chemical Laboratories (ON, Canada) and Robertson Microlit Laboratories (NJ), except for some sulfur analyses that were done on-site by a modified Schöninger flask method . Surface area measurements 6 were done on a Quantchrome Quantasorb BET apparatus; swelling in toluene was volumetrically gauged on a sample in a small graduated cylinder.…”
