Isomerism in d-block metal complexes
In this book so far, we have not mentioned isomerism very often, and most references have been to trans- and cis-isomers, e.g. trans-[CaI2)THF(4] and the trans- and cis-isomers of N2F2. These are geometrical isomers, and our previous discussion of this topic will not be elaborated further here.
Self-study exercises
1. Draw possible structures for the square planar complexes [PtBr2(py)2] and [PtCl3(PEt3)]-and give names to distinguish between any isomers that you have drawn.
2. In [Ru(CO)4(PPh3)], the Ru centre is in a trigonal bipyramidal environment. Draw the structures of possible isomers and give names to distinguish between them.
3. Draw the structures and name the isomers of octahedral [CrCl2(NH3)4]+.
4. Octahedral [RhCl3(H2O)3] has two isomers. Draw their structures and give them distinguishing names.
In this section, we shall be concerned with other types of isomerism exhibited by d-block metal complexes, and we use a classification that goes back to the work of Werner (Figure 1.1).
