| Popis: | Two ytterbium(III) complexes comprising alkynylamidinate ligands, namely bis(η5-cyclopentadienyl)(3-cyclopropyl-N,N′-diisopropylpropynamidinato-κ2N,N′)ytterbium(III), [Yb(C5H5)2(C12H19N2)] or Cp2Yb[(iPr2N)2C—C[triple-bond]C—c-C3H5] (1) and tris(3-phenyl-N,N′-dicyclohexylpropynamidinato-κ2N,N′)ytterbium(III), [Yb(C21H27N2)3] or Yb[(CyN)2C—C[triple-bond]C—Ph]3 (Cy = cyclohexyl) (2) have been synthesized and structurally characterized. Both complexes are monomers; for complex 2, the contribution to the scattering from highly disordered toluene solvent molecules in these voids was removed with the SQUEEZE routine [Spek (2015). Acta Cryst. C71, 9–18] in PLATON. The stated crystal data for Mr, μ etc. do not take these into account. |
