Eight samples from five suppliers have been examined at 100 and 77 K. These differ markedly in the relative doublet contribution to the total spectral area and also in the hyperfine fields characterizing the sextets. The results indicate three distinct types of distribution. One sample from each type has also been examined at 4 K, where the doublet component has vanished and the hyperfine field distribution has become narrow and symmetric. These data are compared with estimates of average core diameters from X-ray line broadening.}, number={4}, journal={JOURNAL OF INORGANIC BIOCHEMISTRY}, author={Knight, B and Bowen, LH and Bereman, RD and Huang, SY and De Grave, E}, year={1999}, month={Apr}, pages={227–233} }

The crystal structure of 2 exhibits a molecular stacking pattern which has alternating Pt and S(thione) atoms forming a one-dimensional chain which suggests the presence of a weak axial interaction between the Pt and S(thione). A correlation exists between the 195Pt NMR chemical shifts and the one-electron oxidation potentials of these complexes. In addition, it is shown that the carbonyl of the dmid2− ligand is not susceptible to alkoxide attack when coordinated to platinum.}, number={2}, journal={INORGANICA CHIMICA ACTA}, author={Keefer, CE and Purrington, ST and Bereman, RD and Knight, BW and Bedgood, DR and Boyle, PD}, year={1998}, month={Nov}, pages={200–208} }
