Crystal structures of two ytterbium(III) complexes comprising alkynylamidinate ligands

Two ytterbium(III) complexes comprising alkynylamidinate ligands, namely bis­(η(5)-cyclo­penta­dien­yl)(3-cyclo­propyl-N,N′-diiso­propyl­propynamidinato-κ(2) N,N′)ytterbium(III), [Yb(C(5)H(5))(2)(C(12)H(19)N(2))] or Cp(2)Yb[((i)Pr(2)N)(2)C—C≡C—c-C(3)H(5)] (1) and tris­(3-phenyl-N,N′-di­cyclo­hexyl­p...

Sumario:Two ytterbium(III) complexes comprising alkynylamidinate ligands, namely bis­(η(5)-cyclo­penta­dien­yl)(3-cyclo­propyl-N,N′-diiso­propyl­propynamidinato-κ(2) N,N′)ytterbium(III), [Yb(C(5)H(5))(2)(C(12)H(19)N(2))] or Cp(2)Yb[((i)Pr(2)N)(2)C—C≡C—c-C(3)H(5)] (1) and tris­(3-phenyl-N,N′-di­cyclo­hexyl­propynamidinato-κ(2) N,N′)ytterbium(III), [Yb(C(21)H(27)N(2))(3)] or Yb[(CyN)(2)C—C≡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.
