The title compounds were obtained by reacting (NH4)2MS4 (M = Mo, W) an
d AgI with excess alpha-methylpyridine or gamma-methylpyridine. The st
ructures can be described as extended networks of -AgS2M- (M = MO, W)
as four-membered rhombs which are alternately parallel and perpendicul
ar all along the polymer chain composed of continuous metal-metal bond
