Three new tetrakis [Rh2(PhNCOCH3)4·xNCR] (R = {2-CH3}C6H4 (x=2), R = {3-CH3}C6H4 (x=1), R = (3-CN)C6H4∞ (x=1)) complexes have been synthesized and characterized. These complexes were characterized by IR and 1H NMR spectroscopies and X-ray crystallography which solved with R1<0.05.
[Rh2(PhNCOCH3)4·2NC{2-CH3}C6H4] was triclinic (a=9.79Å, b=14.79Å, c=16.36Å, α=103.84⁰, β=99.17⁰, γ=99.77⁰, P-1(#2), μCN=2227.78cm-1, Rh-Rh=2.42Å, N-C=1.13Å, 1.14Å, Rh-N=2.34Å, 2.35Å, Rh-N-C=151.6⁰, 152.5⁰, Rh-Rh-N=173.0⁰, 174.6⁰).
[Rh2(PhNCOCH3)4·NC{3-CH3}C6H4] was triclinic (a=11.71Å, b=13.02Å, c=13.40Å, α=72.34⁰, β=66.78⁰, γ=82.74⁰, P-1(#2), μCN=2241.28cm-1, Rh-Rh=2.40Å, N-C=1.14Å, Rh-N=2.16Å, Rh-N-C=166.3⁰, Rh-Rh-N=175.9⁰).
[Rh2(PhNCOCH3)4·2NC{3-CN}C6H4]∞ was triclinic (a=11.88Å, b=13.30Å, c=14.88Å, α=77.98⁰, β=74.61⁰, γ=65.48⁰, P-1(#2), μCN=2233.57cm-1, Rh-Rh=2.41Å, N-C=1.13Å, 1.13Å, Rh-N=2.18Å, 2.38Å, Rh-N-C=166.8⁰, 127.7⁰, Rh-Rh-N=178.4⁰, 175.4⁰).
The bond distances, bond angles and bonding interactions (σ and π) are similar to the metal-carbene bond formed during carbenoid transformations catalyzed by dirhodium(II) compounds.
