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 کاملSynthesis, Characterization and X-Ray Crystal Structure of a Cobalt(III) Complex with 2-Bis(pyridine-2-carboxamido)-4,5-dimethylbenzene Ligand
An octahedral cobalt(III) complex, trans-[(Me2bpb)Co(bzlan)2]ClO4 (1), with H2Me2bpb = N,N’-(4,5-dimethyl-1,2-phenylene)dipicolinamide and bzlan = benzylamine, has been synthesized and characterized by elemental analyses, IR, UV-Vis, and 1H NMR spectroscopy. The structure of this complex has been determined by X-ray crystallography. The Me2bpb2– is a di-anionic tetradentate ligand furnishing a ...
متن کاملTwo azido-bridged cobalt(II) coordination polymers with nicotinate co-ligand: synthesis, structures and magnetic properties.
By utilizing nicotinic acid as a co-ligand, two new azido-bridged cobalt(II) complexes with the formulae [Co(2)(N(3))(nic)(2)Cl(H(2)O)](n) (1) and [Co(N(3))(nic)](n) (2) (nic = nicotinate) have been synthesized under solvothermal condition and structurally characterized. Complex 1 exhibits a rare three-dimensional (3D) Kagomé topology with [Co4] units as connecting nodes. Complex 2 is also a 3D...
متن کاملStructure and Chromotropic Properties of 2-Picolylamine-Ni(II) Complex
A symmetric complex [NiL2(H2O)2]Cl2, where L = 2-picolylamine was synthesized and characterized by spectroscopic and structural methods. Single crystal X-ray studies reveal that the Ni(II) center located in a pseudo-octahedral N4O2 environment with bidentate ligands L positioned in basal and two water molecules in the apical position. The complex is solvatochromic, ionochromic and thermochromic...
متن کاملExperiment 2: Deprotonation/protonation rate constants
where the values of the forward (kd) and reverse (kp) rate constants may be different from those in the ground state because of differences in the properties of the 2-naphthol in these two states (for example, Ka 6= K ∗ a in part I). The objective of this experiment is to determine the deprotonation/protonation rate constants of 2-naphthol in its lowest excited singlet state in aqueous solution...
