Ample amount of 3-D structures are provided in the chapter for facile visualization. Experimental methods for distinguishing the geometrical isomerism provided in the chapter are an important supplement to the study. Similarly, after the discussion on optical isomerism, a note on racemization will ...

with the various forms of isomerism in coordination chemistry. Our focus will be on geometric isomerism, which arises from the three-dimensional arrangement of atoms in space, and optical isomerism, which results from complexes that are mirror images of one another. Although coordination compounds ...
For coordination complexes, many coordination compounds such as [M(en)3]n+ [in which Mn+ is a central metal ion such as iron(III) or cobalt(II)] form enantiomers, as shown in Figure 2. These two isomers will react differently with other optical isomers. For example, DNA helices are ...
The total number of points of attachment of the ligands to the central metal atom/ion is called the coordination number and this can very from two to as many as 16. But the most common coordination number in coordination compounds are 4 and 6. Two common structures are observed for four...
WHEN Pfeiffer 1 , in 1923, suggested that in complex compounds of the type ( LM Cl 2 ) 2 ( L = non-ionic ligand; M = divalent metal, for example, Pt II ), the metal atoms were 'bridged' by halogen atoms as in (I), he also pointed out the possible existence of isomers (II...

An unusual case of symmetry-preserving isomerism. Supramolecular isomerism with polythreaded topology based on [Mo8O26]4- isomers Supramolecular isomerism in coordination compounds: nanoscale molecular hexagons and chains. Supramolecular isomerism, framework flexibility, unsaturated metal center, and porous...
Compounds 1-2, 3-4, and 5-6 are three pairs of linkage isomers since they present the same formula and chain structure and they only differ in the connectivity of the polynitrile ligand bridging the metal ions in the chain: through a N and an O atom (1κN:2κO-isomer) or through...
