摘要:
Five new lanthanide 1-D coordination polymers are reported which are formed from flexible salen type Schiff-base ligands H2L and H2L' (H2L = N, N-1-ethylene bis(salicylideneimine); H2L' = N,N-1-bis(3-methoxysalicylidene) ethylene-1,2-diamine). The polymeric structures are formed by bridging neutral H2L units in the case of {[Ln(2)L(2)(CF3SO3)(H2L)(4)(MeOH)]center dot CF3SO3}(n) (Ln = Eu (1), Nd (2) and Er (3)), and by acetate (OAc-) groups in [Yb-2(L)(2)(OAc)(2)(MeOH)(2)](n) (4) and {[Tb-3(L')(2)(OAc)(5)]center dot Et2O center dot(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.
