Synthesis and Crystal Structure of [Pb(gly)2]n; New lead(II) Coordination Polymer with Glycine Ligand
[Pb(gly)2]n (1) (gly is the abbreviation of Glycine) have been synthesized and characterized by elemental analyses, IR, 1H NMR and 13C NMR spectroscopy. The single crystal structure of 1 show the complex is 2D coordination polymer with octahedral environment that is formed into 3D supramolecule through hydrogen bond. Structural determination of compound 1 reveals the Pb(II) ion is four coordina...
متن کامل4-(N-Propan-2-ylcarbamoyl)pyridinium perchlorate
In the title compound, C(9)H(13)N(2)O(+)·ClO(4) (-), the dihedral angle between the planes of the amide group and the pyridinium fragment is 34.11 (14)°. In the crystal, the cations are connected by N-H⋯O hydrogen bonds between the amide groups into chains extended along the a axis. Hydrogen bonds between the pyridinium N-H group and the perchlorate anions organize the chains into a two-dimensi...
متن کاملDesign and Synthesis of 2-Methyl and 2-Methyl-4-Nitro Imidazole Derivatives as Antifungal Agents
Two series (a and b) of N- substituted heteroaromatic compounds related to clotrimazole were synthesized. Imidazole ring of the clotrimazole was replaced by 2-methylimidazole in series a, and by 2-methyl-4-nitroimidazole in series b. O-cholortrityl moiety of clotrimazole was also replaced by trityl, mono or dimethoxy trityl. Chemical structures...
