Abstract
The crystal and molecular structure of the title compound, C76H64BBrP4Co, is reported. Crystals are orthorhombic, space groupP212121 (No. 19) withZ=4 in a unit cell of dimensionsa=15.342(3),b=18.527(2), andc=22.223(1) Å. The structure was solved by the heavy-atom method and refined by full-matrix least squares toR=0.094 for 2356 unique diffractometer data. The coordination geometry around Co atom is that of a distorted trigonal bipyramid. Each diphos ligand bridges an axial and equatorial coordination site with the bromine atom occupying the remaining equatorial position. The symmetry can only be approximated toC 2 because of the large angular deviations from three-fold symmetry and difference in groups in the equatorial plane. The boron atom of the anion has an approximate tetrahedral configuration.
