Item (2,2 '-bipyridine)saccharinatosilver(I)(Wiley-Blackwell, 2007-12) Hamamcı, Sevim; Harrison, William T.A.; Yılmaz, Veysel Turan; Uludağ Üniversitesi/Fen Edebiyat Fakültesi/Kimya Bölümü.; 0000-0002-2849-3332; L-7238-2018; 7006269202The title complex, [Ag(C7H4NO3S)(C10H8N2)], has a mononuclear structure in which the Ag-I ion is coordinated by two N atoms from 2,2 '-bipyridine and one N atom from saccharinate, forming a distorted T-shaped (or trigonal-planar) AgN3 arrangement. The bite angle of bpy is 71.69 (6)degrees, which contributes significantly to the distortion of the coordination geometry. Molecules are connected by C-H center dot center dot center dot O and pi(bpy)-pi(bpy) interactions with a centroid-centroid separation of 3.6741 (13) angstrom.Item Synthesis, characterization, crystal structures and thermal and fluorescence studies of dinuclear and polymeric silver(I) complexes of 5,5-diethylbarbiturate with 2,5-dimethylpyrazine and piperazine involving Ag-Ag interactions(Springer, 2010-06) Yılmaz, Fatih; Büyükgüngör, Orhan; Harrison, William T.A.; Soyer, Eda; Yılmaz, Veysel Turan; Uludağ Üniversitesi/Fen-Edebiyat Fakültesi/Kimya Bölümü.; 0000-0002-2849-3332; L-7238-2018; 32267686800; 7006269202Two silver(I) complexes, [Ag(dmpyz)(2)][Ag(barb)(2)] (1) and {[Ag(ppz)][Ag(barb)(2)]center dot H2O} (n) (2) (barb = 5,5-diethylbarbiturate, dmpyz = 2,5-dimethylpyrazine and ppz = piperazine), have been synthesized and characterized by elemental analyses, IR, thermal analysis (TG-DTA) and single-crystal X-ray diffraction. Complex 1 consists of [Ag(dmpyz)(2)](+) and [Ag(barb)(2)](-) ions in which the silver(I) ions are linearly coordinated by two dmpyz or two barb ligands. These two ions are connected by strong Ag-Ag interactions (Ag-Ag = 2.896 (1) ). Complex 2 is a 1D coordination polymer in which the silver(I) ions are bridged by the ppz ligands in a linear fashion, leading to a zigzag chain of [Ag(ppz)] (n) (+) , which interacts with the [Ag(barb)(2)](-) units by Ag-Ag interactions of 3.183 (1) . The 1D chains are further assembled to form 3D networks by strong N-H center dot center dot center dot O and OW-H center dot center dot center dot O hydrogen bonds. IR spectra and TG-DTA data are in agreement with the crystal structures. The fluorescent properties of 1 were also evaluated.
