Аннотация:Many carborane derivatives first synthesized during the rapid development of this field of chemistryin the 1960s remained completely uncharacterized by modern spectral and diffraction methods. In this work, a series of C-mercuro derivatives of ortho-carborane 1-PhHg-2-Ph-1,2-C2B10H10 and (2-R-1,2-C2B10H10)2Hg (R = H, Me, Ph) were newly synthesized and characterized by NMR spectroscopy. The molecular crystal structure of bis(2-phenyl-ortho-carboran-1-yl)mercury was determined by single crystal X-ray diffraction.
