Synthesis and Structure of Chromium(II) Complexes Supported by Both a β-Diketiminate and an Amidinate Ligand

The complexes (bis(2,6-diisopropylphenyl)pentane-2,4-ketiminato)(μ 2 -diisopropylacetamidinato) chromium(II) ( 1 ) and (bis(2,6-diisopropylphenyl)pentane-2,4-ketiminato)(μ 2 -dicyclohexylacetamidinato) chromium(II) ( 2 ) have been synthesized and structurally characterized. Complex 1 crystallizes in...

Description
Summary:The complexes (bis(2,6-diisopropylphenyl)pentane-2,4-ketiminato)(μ 2 -diisopropylacetamidinato) chromium(II) ( 1 ) and (bis(2,6-diisopropylphenyl)pentane-2,4-ketiminato)(μ 2 -dicyclohexylacetamidinato) chromium(II) ( 2 ) have been synthesized and structurally characterized. Complex 1 crystallizes in space group Pbcn with crystal cell parameters a  = 10.7183(13) Å, b  = 16.4093(19) Å, c  = 20.687(2) Å, V  = 3,638.3(7) Å 3 and Z  = 4. Complex 2 crystallizes in triclinic space group P -1 with crystal cell parameters a  = 10.750(3) Å, b  = 12.174(3) Å, c  = 16.308(4) Å, α = 75.903(4)°, β = 82.137(4)°, γ = 85.511(4), V  = 2,048.4(8) Å 3 and Z  = 2. The complexes adopt a spiro distorted square planar geometry and have similar structural parameters. Graphical Abstract Two complexes that each possesses both a β-diketiminate and an amidinate ligand were synthesized and structurally characterized.
