Two coordination polymers with a 2D grid network structure of [Cu(L1)]NO 3 ·H 2 O ( 1 ) and [Cu(L1‐2H)](AcOH) 2 · (C 2 H 5 ) 2 O·4H 2 O ( 2 ) were obtained by reaction of the flexible tetradentate ligand 1,2‐bis(4′‐pyridylmethylamino)ethane (L1) with one mol of [Cu(CH 3 CN) 4 ]NO 3 or Cu(OAc) 2 ·H 2 O. The syntheses of a new bridging ligand 1,2‐bis(4′‐pyridylmethyleneamino)ethane (L2) and its copper(I) complexes are described. When L2 reacts with [Cu(CH 3 CN) 4 ]·ClO 4 or [Cu(CH 3 CN) 4 ]·NO 3 , two interesting complexes with an infinite zigzag chain‐like structure [Cu(L2)(CH 3 CN)]NO 3 ( 3 ) and [Cu(L2)(CH 3 CN)]ClO 4 ( 4 ), involving the coordination of an acetonitrile molecule, were obtained. These coordination complexes were characterized by X‐ray crystallography. The results showed that the rigidity of the ligand and the different chemical valence of the transition metal ions have a large effect on the construction of supramolecular frameworks.
