Abstract

The complexes (bis(2,6-diisopropylphenyl)pentane-2,4-ketiminato)(μ2-diisopropylacetamidinato) chromium(II) (1) and (bis(2,6-diisopropylphenyl)pentane-2,4-ketiminato)(μ2-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) Å3 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) Å3 and Z = 2. The complexes adopt a spiro distorted square planar geometry and have similar structural parameters.
