Abstract:

The structure of di-mu-diphenylphosphinatoacetylacetonatochromiumIII, with sixty atoms in the asymmetric unit, was determined by Patterson superposition and Fourier techniques. Two molecules crystallize in a triclinic unit cell with dimensions a 12.64,b 15.57, c 13.35 A., alpha 112.4 degrees, beta 112.50 degrees, gamma 84.2 degrees. The ligands around the chromium atoms conform to octahedral symmetry and the bridge structure, CrOPO2, is a puckered eight-membered ring. Block diagonal least-squares refinement with Cr, P, and O atoms anisotropic resulted in a final R value of 0.09 for 4400 observed reflections. Author
