摘要

Four mercury(II) thiocyanate-organic polymeric complexes, [Hg(mu-4,4-bipy)(SCN)(2)](n) (1), [Hg mu-bpa)(SCN)(2)](n) (2), [Hg(mu-bpe)(SCN)(2)](n) (3), [Hg[mu-bpp)(SCN)2](n) (4) {4,4-bipy = 4,4'-bipyridine, bpa = 1,2-bis(4-pyridyl)ethane, bpe = 1,2-bis(4-pyridyl)ethene and bpp = 1,3-di(4-pyridyl)propane) were prepared from reactions of mercury(II) thiocyanate with four rigid and flexible organic nitrogen donor-based ligands under thermal gradient conditions, brunched tube method. All these compounds were structurally determined by X-ray single-crystal diffraction. The thermal stabilities of compounds 1-4 were studied by thermal gravimetric (TG) and differential thermal analyses (DTA). Solid state luminescent spectra of compounds 1 and 3 indicate intense fluorescent emissions at 430 and 468 nm, respectively. (C) 2007 Elsevier Ltd. All rights reserved.
