Source of material Single crystals of the title compound, K3Na(WC>4)2, were obtained from the reaction of anhydrous sodium tungstate and anhydrous potassium tungstate. The starting mixture Na 2 W04 and K2WO4 with a molar ratio of 1:3 were mixed intimately. The mixture was pressed into a pellet and subsequently heated at
