Ruske and I. Hartmann, J. Prakt. Chem. 18, 146 (1962) was dissolved in 480 g. of pyridine. With rapid stirring at room temperature, 14.4 g. (0.184 mole) of carbon disulfide was added dropwise followed by 15.2 g. (0.083 mole) of anhydrous zinc acetate. The reaction mixture was heated 3 hours at 45°- 50°C, cooled to room temperature, and then diluted with 1 liter water; the precipitated product was filtered and dried in vacuo at room temperature to obtain 33.4 g. of the desired pyridine adduct melting at 205°- 207°C (decomp.). A small analytical sample, recrystallized in methanol, sintered at 209°C and melted with decomposition at 212°-214°C. It had the following anaylsis: Found: C, 26.70; H, 2.74; N, 6.30; S, 19.60; Cl, 31.37; Zn, 9.55%. Calcd for C10H10Cl6N2O2S4Zn . C5H5N: C, 26.65; H, 2.22; N, 6.23; S, 18.95 Cl, 31.54; Zn, 9.68%.
