Chapter 24: Transition Metals and Coordination Compounds
Terms in this set (34)
complex ions are also called
the molecules or ions that bond to the metal are known as
the ____ is the metal and the total number of ligands bonded to it
the complex is a ____ charge salt, which may contain additional cations or anions not bonded to the metal
the number of lone pairs donated to the metal
molecular geometry shape if coordination number is 2
molecular geometry shape if coordination number is 4
square planar or tetrahedral
molecular geometry shape if coordination number is 6
ligands are sometimes referred to as
the formation of complexes favors the ____
the larger K for the bidentate ligand is known as the ____
if K >>1 then
if K <<1 then
compounds with the same formula but either atoms are in a different order (structural) or atoms are in a different spatial arrangement (stereoisomers)
a ____ isomer occurs when a ligand can bond through a different atom
a ____ isomer occurs when the ligands bonded to the metal are exchanged for ones outside of the coordination sphere
a ____ isomer occurs when the spatial orientation of a complex can be changed
an ____ isomer occurs when the mirror image of the complex is non-superimposable
the pair of optical isomers are called
in complexes, the only way to get optical isomerism is with. what?
a 6 coordinate system and two or 3 bidentate ligands
what 2 factors does color depend on?
1) unpaired D electrons
2) ligands bonded to the transition metal ion
compounds must absorb some visible light to have what?
a compounds color can be due to what?
either it absorbs all wavelengths but that color
OR it absorbs on color exclusively (most typical)
unpaired electrons =
paired electrons =
as the ligand donates its electron pair to form the bond, it interacts with the metal's d orbitals
crystal field theory
for octahedral complexes, if small delta then
fill each level first before pairing
for octahedral complexes, if large delta then
fill the lower level completely before moving to upper level
small delta means __spin
large delta means ____ spin
do weak field ligands have small or large delta?
do strong field ligands have small or large delta?
delta is always ____ for tetrahedral complexes so these are always ____ spin
delta is always ____ for square planar complexes so these are always ___ spin
