N2 - Reaction of Ln(NO3)3·6H2O with H2napn (H2napn=N,N′-ethylenebis(2-hydroxy-1- naphthylideneiminato)) and KSCN produces seven new coordination polymers, [La(H2napn) (SCN)(C2H5OH)2(NO 3)2]n (1), [La(H2napn) 2(SCN)(NOM3)2]n (2), and [Ln(H 2napn)1.5(NO3)3]n [Ln=La(3), Sm(4), Eu(5), Dy(6), Er(7)]. Crystal structure analysis reveals that H2napn functions as a bridging ligand, forming a 1-D chain polymer (1) and 2-D open-frameworks (2-7) with lanthanides. Each metal center of 1-7 is nine-coordinate. Lanthanide contraction is observed in 3-7.
