Two new 1,2,3,5-dithiadiazoles, [4-(4Ј-C 5 H 4 N)CN 2 S 2 ] (L 1 ) and [4-(3Ј-C 5 H 4 N)CN 2 S 2 ] (L 2 ), with different pyridyl groups at the 4-position were prepared. As Lewis bases, the dithiadiazoles reacted with Lewis acids via their pyridyl groups to form acid-base adducts with retention of t
