Bi(thipohene)-type ligand and its silver coordination polymers [AgL2] · (X) (L = 1,2-bis((thiophen-3-yl)methylene)hydrazine; )

A novel linking ligand, 1,2-bis((thiophen-3-yl)methylene)hydrazine (L), which contains terminal thiophene rings, was prepared. From ligand L and silver salts AgX, the corresponding 2-D silver coordination polymers [ Ag L 2 ] · ( X ) [ X = ClO 4 - ( 1 ) , SbF 6 - ( 2 ) , PF 6 - ( 3 ) ] could be prepared. All polymers have been constructed by van der Waals contacts, and their structures depend basically on the nature of the counterions used.
