摘要Six new silver(I) double salts containing embedded 1,3-butadiyne-1,4-diide(C-4(2-)) and various types of ancillary heteroaromatic N-donor ligands, namely [{(Ag2C4)(0.5)(AgNO3)(3)(L-1)}center dot H2O](n) (1; L1 = 3-chloropyridine), [(Ag2C4)(2)(AgCF3CO2)(9)(L1)(7)(H2O)](n) (2; L1 = 3-chloropyridine) ' [(Ag2C4)(2)(AgCF3CO2)(9)(L2)(7)(H2O)] (3; L2 = 3-bromopyridine), [{(Ag2C4)(AgCF3CO2)(5)(L3(1.5)(H2O)(2)}center dot H2O](n) (4; L3 = 2-methylpyrazine), [(Ag2C4)(AgCF3CO2)(6)(L4)(6)] (5; L4 = 2-cyanopyridine), and [(Ag2C4)(AgCF3CO2)(10)(L5)(8)] (6; L5 = imidazole) have been synthesized and characterized by X-ray crystallography. Complex 1 exhibits a two-dimensional coordination network in which the basic building unit is a [Ag4C4Ag4] aggregate. Isomorphous complexes 2 and 3 feature a composite-chain structure with trifluoroacetate and halogen-substituted pyridine ligands surrounding a columnar silver backbone. Complex 4 is a three-dimensional coordination framework composed of silver columns cross-linked by external silver atoms and 2-methylpyrazine bridges. Complex 5 contains two nearly identical discrete supramolecular clusters, each with its [Ag4C4Ag4) core stabilized by four bridging 2-cyanopyridine ligands and three peripheral trifluoroacetates at each terminal. Complex 6 is composed of somewhat similar but larger discrete supramolecules, with its [Ag4C4Ag4] core stabilized by trifluoroacetate as well as both inner and peripheral bis(imidazole)silver units.
