Crystal Structure and Electrochemical, Fluorescent and Magnetic Properties of a New Complex [Ag(2,2′-bipy)(C14H9O3)•(C14H10O3)

A novel silver(I) complex [Ag(2,2'-bipy)(C14H9O3)]center dot(C14H10O3) has been synthesized with 2-benzoylbenzoic acid as the ligand. Crystal data for the title complex: monoclinic, space group Cc, a = 27.4089(13), b = 10.2897(5), c = 12.0024(6) angstrom, beta = 111.864(4), M-r = 715.49, V = 3141.5(3) angstrom(3), D-c = 1.513 g/cm(3), Z = 4, mu(MoK alpha) = 0.694 min(-1), F(000) 1456, the final R= 0.0473 and wR = 0.1146. In the title complex, the central Ag(I) ion is located in a triangular coordination environment. The electron transfer is quasi-reversible in the electrode reaction and it shows a strong emission peak in the range of 495 similar to 520 nm under 502 nm excitation. In addition, it displays diamagnetic property from 3 to 300 K.
