Five new coordination complexes, namely [Ag(L)](BF4) (1), [Ag6(L)4(NO3)6] (2), [Ag3(L)4(CH3CN)2](SbF6)3(H2O) (3), [Ag(L)(OOCCF3)] (4) and [Ag(L)(CH3SO3)] (5), have been obtained by the reactions of the ligand 4-(2-oxazolinyl)pyridine (L) with different Ag(I) salts under the same reaction conditions. The frameworks of 1–5 show different structural features: complex 1 is a zigzag chain; complexes 2–4 contain 2D networks with different topologies; complex 5, interestingly, contains both a zigzag chain and a 2D network. The results reveal that the nature of the counteranions, such as their shape and size, coordination ability and coordination mode, has a great effect on determining the resulting structures. Meanwhile, electrospray mass spectrometry (ES-MS) shows the existence of the fragment of a coordination polymer in the solution.
