    • A pure Y-type structure of a ML5 complex has two angles > 120° and one smaller than 120° in the equatorial plane. A T-type structure has two angles at 90° and one angle at 180°. Y/T-forms show aspects of both limiting forms and are unsymmetrical: G. Ujaque, F. Maseras, O. Eisenstein, L. Liable-Sands, A. L. Rheingold, W. Yao, R. H. Crabtree, New J. Chem. 1998, 1493 and ref.

Note, however, that although the formation of five-coordinate complexes from cis-1-Rh with acetonitrile and from cis-1-Ir with THF is not detected, these isomers must be involved in the equilibrium reaction shown in Scheme 2, as the ratio of trans to cis isomers remains constant at all temperatures.
