“…intensities were also measured with use of the Nicolet P3 diffractomcter and a coupled 8(crystal)-28(counter) scan. The methods of selection of scan rates and initial data treatment have been describcd (9,10). Corrections were made for Lorentz polarization effects but not for absorption.…”

127 (1984). The compound dipotassium 3,3,3',3'-tetramethylcystinate trihydrate, K2 [CII,H,,0,N2S2]3H20, has been prepared and characterized by single crystal X-ray diffraction. Crystals were monoclinic, P 2 , , n = 6.160(1), b = 26.473(8), c = 6.193(1) A, P = 113.94(1)", with two formula units in the unit cell. Intensities were measured on a Syntex P2[ diffractometer with use of MoKa radiation. The structure was solved by standard methods and refined to RI = 0.0469, R2 = 0.0472 based on 2303 independent observed reflections. The C-S bonds (1.877(6), 1.891(6) A) are longer than in many similar compounds although the S-S bond (2.040(2) A) is not. The C-S-S-C torsional angle (108.7(3)") is larger than normal in dithiol compounds. Other distances and angles are normal. Two types of potassium coordination are present, one a distorted octahedron, the other a distorted trigonal prism. In addition to the ionic interactions, hydrogen bonds involving the water molecules are important in stabilizing the structure. (108,7(3)") est plus grand que ceux observts normalement dans les dithiols. Les autres distances et les autres angles sont normaux. Le potassium posskde deux types de coordination, I'un est un octakdre deform6 tandis que I'autre est un prisme trigonal dCformC. En plus des interactions ioniques, les liaisons hydrogknes impliquant les molCcules d'eau sont importantes pour de la stabilitC de la structure.[Traduit par le journal]

“…Total background time to scan ratio was 1:1. Methods of treating intensities have been described (Hughes, Krishnamachari, Lock, Powell & Turner, 1977;Lippert, Lock, Rosenberg & Zvagulis, 1977). Three standard reflections collected every 150 reflections (3ii, Rmerg e = 0.030; 402, 0.036; 1i4, 0.033) showed no instrument instability or crystal decay.…”
