Silver(I) Double and Multiple Salts Containing 1,5-Hexadiyne-1,6-diide and Nitrate Ions
Publication in refereed journal



摘要Five new silver(I) double and triple salts containing conformationally flexible 1,5-hexadiyne-1,6-diide (C- CCH2CH2C C-, C6H42-) and nitrate ions, namely Ag2C6H4 center dot 7AgNO(3) ( 1), Ag2C6H4 center dot 3AgNO(3)center dot 2AgF (2), Ag2C6H4 center dot 4AgNO(3)center dot 2L1 (3; L1 = imidazole), Ag2C6H4 center dot 2AgNO(3)center dot 2AgL2 (4; HL2 = pyrazole), and Ag2C6H4 center dot 4AgNO(3)center dot 2L3 (5; L3 = 3,5-dimethylpyrazole), have been synthesized, in which the C6H42- species was found to adopt two distinct configurations: anti in 1 and 3 and gauche in 2, 4, and 5. Complex 1 features an unusual Ag-5 subset of C6H4 superset of Ag-4 aggregate as the basic building unit, and such aggregates are interconnected by the nitrate ions to generate a three-dimensional coordination network. Complex 2 exhibits a three-dimensional coordination network constructed with compact C-6H4 superset of Ag-7 units, nitrate ions, and fluoride ions that assume a mu(3) trigonal-pyramidal coordination mode. In 3, the Ag-4 subset of C6H4 superset of Ag-4 aggregates are stabilized by nitrate groups and imidazole ligands to generate a layer structure. In complex 4, infinite chains each bearing deprotonated pyrazole ligands attached to the silver backbone are weaved by nitrate groups to form a three-dimensional coordination architecture. In 5 the 3,5-dimethylpyrazole ligands coordinate to silver atoms at the upper surface of each coordination layer, and the layers are interconnected to form a three-dimensional supramolecular network via hydrogen bonding.
