TL;DR: The molecular structures of the (p-R-phenyl)dimesitylboranes, which have been determined from single-crystal X-ray diffraction measurements, offer evidence of increased conjugation in the ground state with increased donor strength of the R substituent.

TL;DR: In this article, a series of symmetric compounds of the general form (mes)2 B⇐X⇒B(mes) 2 [mes=mesityl=2,4,6 Me3C6H2; ⇐X ⇒=conjugated organic π system such as −(p-C 6H4)n− or trans-trans−CH=CH-n−, p-C6h4n− CH=CH−CH−, CH− CH−

TL;DR: In this article, the electronic structure and chemical bonding of rare-earth metal borocarbides were analyzed using extended Huckel tight-binding and density functional theory calculations, revealing a rather strong covalency between the metallic matrix and the BC 2 groups and the isolated carbon atoms, respectively.

TL;DR: Gd4B3C4 is the first characterized member of the rare earth metal borocarbide series in which both 1-D and "molecular" 0-D nonmetal atom systems coexist.
