Syntheses, structures, and photoluminescence of 1-D lanthanide coordination polymers

Xiaoping Yang, Richard A. Jones, Joseph H. Rivers and Wai-Kwok Wong

Five new lanthanide 1-D coordination polymers are reported which are formed from flexible salen type Schiff-base ligands H2L and H2L (H2L = N,N1-ethylene bis(salicylideneimine); H2L = N,N1-bis(3-methoxysalicylidene)ethylene-1,2-diamine). The polymeric structures are formed by bridging neutral H2L units in the case of {[Ln2L2(CF3SO3)(H2L)4(MeOH)]·CF3SO3}n (Ln = Eu ( 1), Nd ( 2) and Er ( 3)), and by acetate (OAc-) groups in [Yb2(L)2(OAc)2(MeOH)2]n ( 4) and {[Tb3(L)2(OAc)5]·Et2O·(MeOH)0.5}n ( 5). The structures of 1–5 were determined by single crystal X-ray crystallographic studies and the luminescence properties of 1 and 5 in MeOH solution were determined.
