Chromium(III) Aquo Complexes with a Quinquedentate, Quadridentate, Tridentate, Bidentate, or Unidentate Tetraethylenepentaamine Ligand

摘要

The new complexes Cr(tetren)OH23+, Cr(tetrenH) (OH2)24+, Cr(tetrenH2) (OH2)35+, Cr(tetrenH3) (OH2)46+, and Cr(tetrenH4) (OH2)57+, four of which have a protonated #x201C;partially unwrapped#x201D; tetraethylenepentaamine ligand, have been synthesized, isolated in aqueous solution, and characterized. Their d-d absorption maxima and minima are reported
