Abstract: Two mononuclear lanthanide complexes, [(L)LnIII(Ph3PO)Cl]·CH3OH] [LnIII = Dy (1) and Er(2)], are isolated employing a pyridine-based ligand, [2,2'-{(1E, 1'E)-pyridine 2,6-diylbis(methaneylylidine}bis(azaneylylidine)diphenol] (H2L) and triphenylphosphine oxide. Both complexes are characterized by single-crystal X-ray diffraction studies. Pseudo-pentagonal bipyramidal… read more here.

Abstract: The exposure of CrCl2(THF)2 to 1 equiv. of TEMPO and 1 equiv. [TEMPO]Na afforded (η2-O,N-TEMPO)2CrCl (1, 67%); addition of [TEMPO]Na to 1 yielded (η2-O,N-TEMPO)2Cr(TEMPO) (2). Both 1 and 2 exhibit pseudo-pentagonal planar (PPP) geometry, instead… read more here.
