Description
Summary:By the interaction of [Rh 2 (COE) 4 (μ-Cl) 2 ] (COE = cyclooctene) with 1,2-bis[(2,6-diisopropyl phenyl)imino]acenaphthene (dpp-bian) new binuclear complex [Rh 2 (dpp-bian) 2 (μ-Cl) 2 ]·2.72CH 2 Cl 2 is obtained. The crystal structure is determined by the single crystal X-ray diffraction analysis. Compound 1 ·2.72CH 2 Cl 2 crystallizes in the orthorhombic crystal system (space group Pnma ) with unit cell parameters a  = 51.200(3) Å, b  = 22.3795(13) Å, c  = 12.8631(8) Å, V  = 14739.0(16) Å 3 , R  = 0.0536. Each rhodium atom has a distorted square-planar environment formed by two dpp-bian N atoms and two bridging Cl atoms. Density functional theory calculations predict the existence of two isomers of the [Rh 2 (dpp-bian) 2 (μ-Cl) 2 ] complex with similar formation energies.
