Background/Objective In the current study, we aimed to explore the effects of rice bran oil (RBO) in adjunct to conventional medical therapy on left ventricular ejection fraction (LVEF), cardiometabolic risk...

Two substituted 2,2 0 -bipyridine lead(II) complexes, [Pb(5,5 0 -dm-2,2 0 -bpy)(tfac) 2 ] n (1) (5,5 0 -dm-2,2 0 -bpy ¼ 5,5 0 -dimethyl-2,2 0 -bipyridine and tfac ¼ trifluoroacetate) and [Pb 2 (4,4 0 -dmo-2,2 0 -bpy) 2 (ftfa) 4 ] (2) (4,4 0 -dmo-2,2 0 -bpy ¼ 4,4 0 -dimethoxy-2,2 0 -bipyridine and ftfa ¼fur-oyltrifluoroacetonate), have been synthesized and characterized by elemental analysis, IR, 1 H NMR, and 13 C NMR spectroscopies, thermal behavior, and X-ray crystallography. Complexes 1 and 2 are 1D coordination polymer and dinuclear complex, respectively. The supramolecular features in these complexes are guided by weak directional intermolecular interactions.

Three substituted 2,2'-bipyridine adducts of lead(II) thenoyltrifluoroacetonate, [Pb(4,4'-dm-2,2’- bpy)(ttfa)2]2, 1, [Pb(5,5' -dm-2,2’-bpy)(ttfa)2]2, 2, and [Pb(4,4'-dmo-2,2’-bpy)(ttfa)2], 3, (4,4’ -dm- 2,2’-bpy, 5,5’-dm-2,2’-bpy, 4,4’-dmo-2,2’-bpy and ttfa are the abbreviations for 4,4’-dimethyl-, 5,5’-dimethyl-, and 4,4’-dimethoxy-2,2’-bipyridine, and thenoyltrifluoroacetonate, respectively) have been synthesized, characterized by elemental and thermal analysis, IR and 1H- and 13C-NMR spectroscopy, and studied by X-ray crystallography. The supramolecular features in these complexes are guided/controlled by weak directional intermolecular interactions.
