Bi(thipohene)-type ligand and its silver coordination polymers [AgL2] · (X) (L = 1,2-bis((thiophen-3-yl)methylene)hydrazine; X=ClO4-,SbF6-,PF6-)

A novel bi(thipohene)-type ligand, 1,2-bis((thiophen-3-yl)methylene)hydrazine (L), was prepared. From ligand L and silver salts AgX, three 2-D silver coordination polymers [AgL2]·(X)[X=ClO4-,SbF6-,PF6-] could be prepared. All polymers have been constructed by van der Waals contacts.
