Abstract
Bis{μ-[(dimercaptomethylene)propanedinitrilato-S,S‘]}tetrakis(4-methylpyridine)dizinc(II)−chloroform was obtained by the reaction of ZnCl2 with (NC)2CCS2K2 in a solution of 4-methylpyridine, EtOH, and CHCl3. The zinc atom in the dimer has a tetrahedral geometry. Each of the two (dimercaptomethylene)propanedinitrilato S atoms bridges two bis(4-methylpyridine)zinc moieties to give an eight-membered ring even though an adduct has effectively been formed. The Zn−N bond lengths are 2.035(4) and 2.077(3), A and those of Zn−S are 2.317(1) and 2.321(1) A, respectively.
