Reactivity of M(en)Cl2 (M=PdII/PtII, en=1,2-diaminoethane) with N,N′-bis(salicylidene)-p-phenylenediamine: Binding with hexafluorobenzene
摘要:
Schiff base N,N'-bis(salicylidene)-p-phenytenediamine (LH2) complexed with Pt(en)Cl-2 and Pd(en)Cl-2 provided [Pt(en)L](2).4PF(6) (1) and Pd(Salen) (2) (Salen = N,N'-bis(salicylidene)-ethylenediamine), respectively, which were characterized by their elemental analysis, spectroscopic data and X-ray data. A solid complex obtained by the reaction of hexafluorobenzene (hfb) with the representative complex I has been isolated and characterized as 3 (1 - hfb) using UV-Vis, NMR (H-1, C-13 and F-19) data. A solid complex of hfb with a reported Zn-cyclophane 4 has also been prepared and characterized 5 (4 - hfb) for comparison with complex 3. The association of hfb with 1 and 4 has also been monitored using UV-Vis and luminescence data. (C) 2007 Elsevier Ltd. All rights reserved.
