Coordination Chemisrty

construction & Isomerism in Coordination Complexes Isomers: compounds with the same molecular formula whole incompatible Structural Isomers that differ in which molecules ar bonded to the misdirect Structural isomers: [Cr( body of water)5Cl]Cl2 water pee pee H2O Cr H2O Cl Cl Cl H2O H2O arrangements of atoms. Stereoisomers Same atoms atomic number 18 bonded to the Metal, simply in opposite spatial arrangements vs [Cr(H2O)6]Cl3 H2O Cr H2O H2O H2O Cl3 Green Linkage isomers : (structural isomers) [Co(NH3)5NO2]Cl2 vs Violet [Co(NH3)5ONO]Cl2 Stereoisomers - may be nonrepresentational or optical Geometric: different geometric arrangements of same ligands Ex. [Pt(NH3)2Cl2] Squargon planar geometry 2 geometric isomers: Cis Trans cis-platin binding to DNA  [Co(NH3)4Cl2]Cl ii geometric isomers: cis & trans cis isomer cis isomer (rotated 90°) trans isomer [Co(NH3)3Cl3] two geometric isomers: facial & meridional trans i somer fac Optical Isomers (Enantiomers) mer differ precisely in that they are non-superimposable mirror images.

(like left and remedy hands) Objects that are not superimposible on their mirror images are said to be Chiral (they posses the quality of handedness) amino acidsare chiral: Chiral carbon: A carbon atom in a molecule is chiral if 4 different groups are attached to the C. Ex. CHBrClF Chirality of a metal complex with chelate cast: [Co(en)3]3+ : The chelate rings in [Co(en)3]3+ make thecomplex ion chiral. The optical isomers (or enantiomers) differ only in that they are non-superi mposable mirror images. (like left and right! hands) Chiral molecules are optically active the enantiomers rotate plane polarized hang equally, but in opposite directions. Other physical properties are the same for enantiomers (optical isomers). 1. How legion(predicate) geometrical isomers are there for [Cr(H2O)4Cl2]+ ? 2. Draw the isomers (geometrical & optical) for [Co(en)2Cl2]+. electronic Structure in Coordination Complexes Ligand Field...If you want to get a amply essay, point it on our website: OrderCustomPaper.com
