A novel heteroheptanuclear metal string complex was synthesized by using nickel and ruthenium metal ions to explore the electronic structure and magnetic property.
Three novel oligo-α-pyridylamino ligands, tripyridyldi-amine (H2tpda), tetrapyridyltriamine (H3teptra), pentapyridyltetramine (H4peptea) are synthesized; the crystal structures of their metal complexes with the all-
