Synthesis, structure and near-infrared luminescence of neutral 3d–4f bi-metallic monoporphyrinate complexes
Abstract
The interaction of cationic lanthanide complexes [Ln(porp)(H2O)3]+ (Ln = Er or Yb; porp = porphyrinate) with sodium (cyclopentadienyl)tris(diethylphosphito)cobaltate (NaLOEt) gives the neutral 3d–4f bi-metallic porphyrinate complexes, [(LOEt)Ln(porp)]. X-Ray structural analyses reveal that these complexes are seven-coordinate with the three oxygen atoms of the O3-tripodal
