Abstract

Inorganic-organic hybrids with mixed halo atoms or organically coordinated halometal-complex cations are rare. A series' of haloplumbate hybrids with these structural features, [Cu(phen) 2Cl] n(PbCl 3) n (phen = 1,10-phenanthroline) (1), [Cu(phen) 2Cl] n[PbClI(Cl 0.5I 0.5)] n (2), and [Cu(phen) 2I] n(PbI 3) n (3), have been solvothermally synthesized using phen coordinated halocopper(II) complexes as templates and balance cations. Their haloplumbate ions all show 1-D chain structures. Compounds 1-3 feature the hybridization of inorganic-organic hybrids: 1) their absorption edges fall in the range of those of semiconductors, which is typical for bulk lead(II) halides, but show a red shift compared with those of the latter; 2) bulk lead(II) halides are nonluminous upon UV irradiation, but introduction of the phen coordinated halocopper(II) complexes as templates enable the hybrids to emit blue light. Their luminescent intensities gradually decrease with the increase of I content, which indicates the potential to design and syntheses of new luminescent halide materials by means of variation of halo atoms and that iodoplumbates are not good candidates for luminescent materials. © 2012 Elsevier B.V.
