title: Homoleptic lanthanide(II)-bis(guanidinate) complexes, [Ln(Giso)(2)] (Giso = [(ArN)(2)CN(C(6)H(11))(2)](-), Ar = C(6)H(3)Pr(i)(2)-2,6): planar 4-coordinate (Ln = Sm or Eu) vs distorted tetrahedral (Ln = Yb) geometries.
abstract: The first homoleptic lanthanide(II)-guanidinate complexes have been prepared and shown to have differing coordination geometries (including unprecedented examples of planar 4-coordination) that depend on the size of the lanthanide metal.
