Description
Summary:Based on the use of [Ni(3‐pytpy)2][BF4]2 (3‐pytpy=4′‐(3‐pyridyl)‐2,2′:6′,2″‐terpyridine) (1) as expanded 3, 3′‐N, N′‐rodlike building blocks and CdII atoms as metal “nodes”, two novel NiII‐CdII heterometallic compounds [Ni(3‐pytpy)2Cd2Cl6] (2) and [Ni(3‐pytpy)2Cd(NCS‐κN)4]·CH3OH (3) have been synthesized under different conditions. In the precursory complex 1, NiII atom is coordinated by the tpy domains of two 3‐pytpy ligands, while the pyridyl tails remain uncoordinated. In compound 2, [Ni(3‐pytpy)2]2+ adopting cis‐conformation bridges two four‐coordinated CdII into trinuclear structure. In compound 3, [Ni(3‐pytpy)2]2+ adopting trans‐conformation connects six‐coordinated CdII into 1D chain and the chains were packed into double‐chains through face‐to‐face π‐π stacking interactions.
