Abstract
The preparation and the crystal and molecular structure of the title complex are reported. The coordination polyhedron is that of a distorted capped octahedron Csub(3v) symmetry). The technetium atom is seven-coordnate and bonded to three phosphine ligands (capped face), three chlorine ligands (uncapped face), and to the carbonyl group, which occupies the unique capping position. Crystals are monoclinic, space group P2/sub 1//c, with cell dimensions a = 11.732(9), b = 11.807(9), c = 23.588(12) A, and ..beta..103.42(8)/sup 0/. The structure has been refined by least squares to a conventional R of 0.093 for 1 794 observed reflections. Metal-ligand bond lengths are: Tc-CO 1.86(2), Tc-C1 2.48(1). and Tc-p 2.44(1) A. Seven coordinate complexes are briefly reviewed: in particular, a description of Csub(3v) symmetry and its distortions has been developed in terms of repulsion theory and the angular-overlap model.
