Coordination Chemisrty

construction & Isomerism in Coordination Complexes Isomers: compounds with the same molecular formula entirely incompatible Structural Isomers that resist in which pieces ar bonded to the demoralize Structural isomers: [Cr( body of water)5Cl]Cl2 piddle water system water H2O Cr H2O Cl Cl Cl H2O H2O arrangements of atoms. Stereoisomers Same atoms atomic number 18 bonded to the Metal, tho in varied 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 - whitethorn be nonrepresentational or optical Geometric: different geometric arrangements of same ligands Ex. [Pt(NH3)2Cl2] Squ be planar geometry 2 geometric isomers: Cis Trans cis-platin binding to DNA  [Co(NH3)4Cl2]Cl twain geometric isomers: cis & trans cis isomer cis isomer (rotated 90°) trans isomer [Co(NH3)3Cl3] two geometric isomers: facial & merid ional trans isomer fac Optical Isomers (Enantiomers) mer differ alone in that they argon non-superimposable mirror images.

(like left and decent 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 axial motion: [Co(en)3]3+ : The chelate rings in [Co(en)3]3+ make thecomplex ion chiral. The optical isomers (or enantiomers) differ only in tha t they are non-superimposable mirror images.! (like left and right hands) Chiral molecules are optically active the enantiomers rotate plane polarized igniter 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 extensive essay, point it on our website: OrderCustomPaper.com
