A remarkable Cr(iii) organometallic compound formed by an unprecedented rearrangement of a formamidinate anion
Abstract
In addition to a quadruply bonded dichromium(II,II) compound of unusual structure, we have obtained a dinuclear, antiferromagnetically coupled, CrIII complex [Cr2(μ-OMe)2(η3-N,C,N′ -H2DpyF)2Cl2·MeOH, H2DpyF = CH(NH-pyridyl)2] containing a transformed formamidinate group in which the central carbon atom has changed from sp2 to sp3 hybridization and Cr–C bonds have been formed; details of the crystal structure of the organometallic compound are given here.
