Abstract

Reactions of N,N′-bis(salicylidene)-1,2-cyclohexanediamine (H₂L) with mixed lanthanide counterions of LnCl₃·6H₂O and Ln(NO₃)₃·6H₂O afford four lanthanide coordination polymers, e.g. {Dy(H₂L)_1.5(NO₃)₃]·5CHCl₃·CH₃OH}_n (1) and {[Ln(H₂L)_1.5(NO₃)₂Cl]·2CH₂Cl₂}_n [Ln = Ho (2), Er (3) and Lu (4)]. X-ray crystallographic analysis reveals that H₂L effectively function as a bridging ligand possessing two-dimensional (2D) network frameworks. Magnetic analysis reveals that complex 1 exhibits slow magnetic relaxation. The luminescence of complex 1 exhibits luminescence of the ligand, complex 2 and 3 show characteristic near-infrared (NIR) emission of holmium(III) and erbium(III) ions.
