摘要：

The coordination chemistry of the long conjugated bidentate ligands 1,2-bis(3-pyridyl)butadiyne (L1) and 1,2-bis(4-pyridyl)butadiyne (L2) with M(hfac)(2) (M = Cu, Mn, Zn; hfac = hexafluoroacetylacetonate) is investigated. Four new coordination polymers are prepared by solution reaction sand are fully characterized by infrared spectroscopy, elemental analysis, thermogravimetric analysis, and single-crystal X-ray diffraction. [Cu(L1)(hfac)(2)](n) (1), [Mn(L1)(hfac)(2)](n) (2) and [Zn(L1)(hfac)(2)](n) (3) are obtained by combination of L1 with Cu(hfac)(2).H2O, Mn(hfac)(2).3H(2)O and Zn(hfac)(2).2H(2)O, respectively, in a methylene chloride/methanol mixed-solvent system. Compounds 1-3 are isostructural and adopt a one-dimensional zigzag chain structural motif, consisting of alternating stacking of L1 and hfac molecules along the crystallographic-axis O...H-C hydrogen-bonding interactions in 1-3 play a significant role in aligning the polymer in a two-dimensional network. [Mn(L2)(hfac)(2)](n) (4) is obtained from the reaction of L2 with Mn(hfac)(2) in an acetone/methylene chlroide/methanol mixed-solvent system. The structure features a network of one-dimensional linear chains.
