RISA 1,2-dibenzoyl-cyclopentadiene derivative as a new potential chelating agent in geological materials
Year: 2007
Abstract:
In this paper, 2,3-bis(p-methoxybenzoyl)cyclopentadiene(DPMBCP) has been studied as a chelating agent and pKa value was determined by means of spectrophotometric measurement. The sigmid curve of optical density agents pH ...

Seven and eight-coordinate Fe(III) complexes containing pre-organized ligand 1,10-phenanthroline-2,9-dicarboxylic acid: Solvent effects, supramolecular interactions and DFT calculations
Year: 2018
Abstract:
-ray diffraction. On the basis of crystallographic data, compounds 1 and 2 are very rare seven- and eight-coordination iron complexes and show distorted pentagonal bipyramidal (PBP) and distorted dodecahedron (DD) geometry around the metal centres, respectively...
