Abstract

The crystal structure of a new polymorphic modification of tetrakis(pentafluorophenyl)diboroxane (C6F5)2BOB(C6F5)2 was determined by X-ray single crystal structure analysis. A comparison of the calculated crystal densities of the monoclinic and triclinic modifications at 150 K suggests the metastability of the monoclinic modification. Molecules of the different polymorphic modifications have similar characteristics and conformations, while the polymorphism manifests itself primarily in different crystal packings.
