Studies on organolanthanide complexes. Part 56. Formation of ion-pair complexes [Na·3phen]+[Ln(C5H5)3Cl]–·phen (Ln = La, Pr or Nd; phen = 1,10-phenanthroline) and crystal structure for Ln = Pr

Abstract

In the presence of 1,10-phenanthroline (phen), lanthanide chlorides LnCl3 reacted with cyclopentadienylsodium to give the novel complexes [Na·3phen]+[Ln(C5H5)3Cl]–·phen (Ln = La, Pr or Nd). In the praseodymium case, crystal structure analysis showed that the complex was an Organolanthanide ion pair. In the anion the central metal is co-ordinated to three cyclopentadienyl rings and a chlorine atom, forming a distorted tetrahedron. In the cation the sodium atom is co-ordinated to six nitrogen atoms from three phenanthrolines, to form a distorted octahedron.
