Abstract

The title compound [MeLiPrCoCH2Si(CH3)3 MeLiPr = 2,4-pentane-N,N′-bis(2,6-diisopropylphenyl) ketiminato] possesses trigonal planar geometry and crystallizes in monoclinic space group P21/n with crystal cell parameters a = 10.6155(14) Å, b = 21.279(3) Å, c = 14.8057(19) Å, β = 97.196(2)°, V = 3,318.1(7) Å3, and Z = 4. The title compound is the second reported three coordinated 13 valence electron Co(II) alkyl complex and the first such complex reported with an asymmetrically bonded alkyl group. The steric effects are discussed in comparison of known similar structures of Fe, Co, and Zn.
