摘要

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 Cd-II atoms as metal "nodes", two novel Ni-II-Cd-II heterometallic compounds [Ni(3-pytpy)(2)Cd2Cl6] (2) and [Ni(3-pytpty)(2)Cd(NCS-kappa N)(4)]center dot CH3OH (3) have been synthesized under different conditions. In the precursory complex 1, Ni-II 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 Cd-II into trinuclear structure. In compound 3, [Ni(3-pytpy)(2)](2+) adopting trans-conformation connects six-coordinated Cd-II into 1D chain and the chains were packed into double-chains through face-to-face pi-pi stacking interactions.
