Quiz three Flashcards
Isoelectric
same electron configuration
Ligand is a…
lewis base (base is donor) which attacks the metal acting as lewis acid (acid is recipient)
Primary coordination sphere
ligands that are directly attached to metal
n vs u
u is for bridged, n is dentating (n^x where x is dentation #)
Hard-Soft Acid Base theory (which are which?)
Hard to hard (OF), soft to soft (CPS)
bigger is softer
dative bond
both electrons that form the bond are from one atom
ambidentating ligand
ambidextrous
two or more different atoms from one compound contribue dentation. N-O for example
X crown Y
x denotes number of atoms, y denotes number of specific atom.
Cis vs Trans
fac vs mer
cis 90 degrees
trans opposite
fac facial (all on one half ex trig pyr)
mer (meridian) all in one plane
delta vs lambda
delta rotates clockwise
rotations traditionally from front to back
linkage isomerism
same ligand can coordinate at two two different atoms
stereo isomers
same atoms, different arrangements
optical isomers
two non-superimposable (chiral) structures
ionization isomer
ligand and counter ion switched
hydrate isomers
one ligand is water, swap with counterion
coordination isomers
same empirical formula, different complex ions
edta
6 binding sites if deprotonates
2 from nitrogen (one on each of the two central carbons)
4 from carboxylic acid groups (2 alpha to each N)
