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, P1̄; a =10.292(4), b = 10.794(4), c = 11.399(5) Å; α = 98.894(5), β = 102.360(6), γ =
90.319(5)°; Z = 2), [Ag(L9)]SbF6 (2) (orthorhombic, Cmca; a = 19.059(9), b = 12.922(6), c = 15.609(7) Å; Z =
8), [Ag(L9)]BF4 (3) (orthorhombic, Cmca; a = 19.128(3), b = 12.6042(18), c = 28.003(4) Å; Z = 16), [Ag(L9)]ClO4
(4) (monoclinic, P21/c; a = 8.5153(16), b = 19.722(4), c = 10.320(2) Å; β = 105.307(3)°; Z = 4), [Ag(L10)]SO3CF3 (5) (triclinic, P1̄; a = 9.0605(13), b = 10.4956(15), c = 10.8085(16) Å; α = 101.666(2), β = 109.269(2),
γ = 100.944(2)°; 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) Å; β = 102.541(3)°; Z = 8), and {[Ag2(L10)2(H2O)](ClO4)2}·o-xylene (7) (monoclinic, P21/c; a =
8.1460(10), b = 17.326(2), c = 30.345(4) Å; β = 97.71°; 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.
