Syntheses, thermal analyses, crystal structures and antimicrobial properties of silver(I)-saccharinate complexes with diverse diamine ligands
چکیده انگلیسی

Five new silver(I)-saccharinate complexes [Ag2(sac)2(tmen)2] (1), [Ag2(sac)2(deten)2] (2), [Ag2(sac)2(dmen)2] (3), [Ag(sac)(N,N-eten)] (4), and [Ag(sac)(dmpen)]n (5); (sac = saccharinate, tmen = N,N,N′,N′-tetramethylethylenediamine, deten = N,N′-diethylethylenediamine, dmen = N,N′-dimethylethylenediamine, N,N-eten = N,N-diethylethylenediamine and dmpen = 1,3-diamino-2,2-dimethylpropan) have been synthesized and characterized by elemental analyses, IR, thermal analyses, single crystal X-ray diffraction and antimicrobial activities. The crystallographic analyses show that all the complexes crystallize in monoclinic space group P21/c. In 1, the sac ligand acts as a bridge to connect the silver centres through its imino N and carbonyl O atoms forming an eight-membered bimetallic ring in a chair conformation. Complex 2 has also a dimeric structure in which the monomeric [Ag(sac)(deten)] units are linked by Ag⋯Ag interactions. In 3, saccharinate ligand acts as a bridging bidentate ligand between two silver(I) centres through sulfonyl group and imino N atom, forming an alternating polymeric chain through the direction [0 1 0]. In 4, the inter-molecular N–H⋯O hydrogen bonds form one-dimensional polymeric chains through the a   axis, and these linear chains are inter-connected to each other by N–H⋯O hydrogen bonds, which produce a chain of edge-fused R44(16) and R22(12) rings along [1 0 0]. Complex 5 is a coordination polymer in which the monomeric [Ag(dmpen)(sac)]n units are linked by Ag⋯Ag interactions, and the dmpen ligand acts as a bridge between the silver(I) ions, forming a two-dimensional network parallel to the (1 0 0) plane.

Five new silver(I) complexes of the formula [Ag2(sac)2(tmen)2] (1), [Ag2(sac)2(deten)2] (2), [Ag2(sac)2(dmen)2]n (3), [Ag(sac)(N,N-eten)] (4) and [Ag(sac)(dmpen)]n (5) have been prepared and characterized by elemental analyses, IR, thermal analyses, single crystal X-ray diffraction and antimicrobial activities.Figure optionsDownload as PowerPoint slide
