Abstract

Refinement converged at R,= 0.069 for 67 refined parameters and 898 observables (F, 4.0 u (FJ). 7b is a trischelate with the ligands bound exclusively by A1-P bonds (AI-P= 2.495 (2) A). Crystallographic D3 symmetry is imposed on the molecule. The Alps coordination geometry is almost halfway between octahedral and trigonal prismatic as manifested by a trigonal twist angle of 35.9" which compares with 60" for a regular octahedron and 0" for ...
