title: Organometallic coordination polymers generated from bent Bis(acetylenylphenyl)oxadiazole ligands and Ag(I) salts.
abstract: Two new bent oxadiazole bridging benzoacetylene ligands 2,5-bis(4-ethynylphenyl)-1,3,4-oxadiazole (L9) and 2,5-bis(3-ethynylphenyl)-1,3,4-oxadiazole (L10) were synthesized. The coordination chemistry of them with various inorganic Ag(I) salts has been investigated. Seven new coordination polymers were prepared by solution reactions and fully characterized by infrared spectroscopy, elemental analysis, and single-crystal X-ray diffraction. [Ag2(L9)](SO3CF3)2 (1) (triclinic, P; a =10.292(4), b = 10.794(4), c = 11.399(5) A; alpha = 98.894(5), beta = 102.360(6), gamma = 90.319(5) degrees ; Z = 2), [Ag(L9)]SbF6 (2) (orthorhombic, Cmca; a = 19.059(9), b = 12.922(6), c = 15.609(7) A; Z = 8), [Ag(L9)]BF4 (3) (orthorhombic, Cmca; a = 19.128(3), b = 12.6042(18), c = 28.003(4) A; Z = 16), [Ag(L9)]ClO4 (4) (monoclinic, P2(1)/c; a = 8.5153(16), b = 19.722(4), c = 10.320(2) A; beta = 105.307(3) degrees ; Z = 4), [Ag(L10)]SO3CF3 (5) (triclinic, P; a = 9.0605(13), b = 10.4956(15), c = 10.8085(16) A; alpha = 101.666(2), beta = 109.269(2), gamma = 100.944(2) degrees ; Z = 2), [Ag(L10)(H2O)(0.5)]BF4.0.5H2O (6) (monoclinic, C2/m; a = 32.180(6), b = 17.027(3), c = 8.1453(15) A; beta = 102.541(3) degrees ; Z = 8), and {[Ag2(L10)2(H2O)](ClO4)2}.o-xylene (7) (monoclinic, P2(1)/c; a = 8.1460(10), b = 17.326(2), c = 30.345(4) A; beta = 97.71 degrees ; Z = 4) were obtained by the combination of L9 and L10 with various Ag(I) salts in a benzene/methylene chloride mixed solvent system. In addition, the luminescent and electrical conductive properties of these new compounds were investigated.
