摘要
Treatment of the lithium β-diketiminate [Li{N(R)C(NMe2)C(H)C(NMe2)N(R)}]2 (1) (R=SiMe3) with KOBut, KOH·H2O and CoCl2 in tetrahydrofuran gave in good yields the RO bridged β-diketiminato Co complex [Co{N(H)C(NMe2)C(H)C(NMe2)N(R)-( μ-OR)}]2 (2) at ambient condition. The crystal data of (2) are as follows: crystal system, monoclinic; space group, P121/n1; a=0.963 9(3) nm, b=1.077 2(3) nm, c=2.025 0(6) nm, V=2.102 5(10) nm3, Z=2, Dc=1.186 g·cm-3, F(000)=804, μ(Mo Kα)=0.934 mm-1, R1=0.047 8, wR2=0.097 9. In solid state, complex (2) is a dimer bridged by RO (R=SiMe3) group and the two Co2+ are in distorted tetrahedron. CCDC: 249253.
