  • 24. 4: Isomerism in Coordination Complexes - Chemistry LibreTexts
    Isomers are compounds with the same molecular formula but different structural formulas and do not necessarily share similar properties There are many different classes of isomers, like stereoisomers, enantiomers, and geometrical isomers There are two main forms of isomerism: structural isomerism and stereoisomerism (spatial isomerism)

  • trans-1,2-Diaminocyclohexane - Wikipedia
    trans-1,2-Diaminocyclohexane is an organic compound with the formula C 6 H 10 (NH 2) 2 This diamine is a building block for C2 -symmetric ligands that are useful in asymmetric catalysis [1] A mixture of all three stereoisomers of 1,2-diaminocyclohexane is produced by the hydrogenation of o -phenylenediamine It is also side product in hydrogenation of adiponitrile The racemic trans isomer
  • Isomerism in Coordination Compounds
    The earliest examples of stereoisomerism involve complexes of Co (III) In 1889, Jorgensen observed purple and green salts of [CoCl 2 (en) 2]+, which Werner later correctly identified as the cis- and trans- geometric isomers In 1911, the first resolution of optical isomers was reported by Werner and King for the complexes cis- [CoX (NH 3) (en) 2] 2+, where X=Cl- or Br-

  • Geometric Optical Isomers in Coordination Complexes
    Optical and geometrical isomers Geometric isomerism in square planar complexes Stereoisomers are compounds which have the same structural formula but the atoms are arranged differently in 3d space You may recall from the work you have already done in organic chemistry that there are two types of stereoisomers, these are: Optical isomers Geometrical isomers such as cis trans and E Z isomers
