Preparation, and crystal and molecular structure of π-cyclopentadienyl-η-(tetraphenylborato)ruthenium(II)

Abstract

The preparation of the title compound is reported. Crystals are monoclinic, a= 9·527(4), b= 15·381(6), c= 15·518(7)Å, β= 105·09(5)°, Z= 4, space group P2₁/c. The structure was determined by Patterson and Fourier methods from diffractometer data and refined by least-squares methods to a final R of 0·032 for 2048 reflections. The ruthenium atom is sandwiched between the cyclopentadienyl ring and one of the phenyl rings of the tetraphenylborate anion. The rings are planar, parallel, and 3·52 Å apart.
