Coordination Complexes

Question 1

coordination compound

Answer 1

central metal atom surrounded by one or more ligands

Question 2

ligand

Answer 2

an atom or molecule that can have an independent existence

Question 3

e- pair acceptor

Answer 3

lewis acid

Question 4

e- pair donator

Answer 4

lewis base

Question 5

ligands are lewis ?

Answer 5

bases

Question 6

metals are lewis ?

Answer 6

acids

Question 7

Primary/inner coordination sphere

Answer 7

ligands bonded directly to metal

Question 8

stereoisomers

Answer 8

same connectivity, different spatial arrangement

Question 9

Four types of Geometric stereoisomers

Answer 9

cis, trans, mer, fac

Question 10

Chiral molecule

Answer 10

has no improper rotation axis

Question 11

denticity

Answer 11

of different lewis base donors within a ligand that can coordinate with lewis acid metal

Question 12

Two types of structural/constitutional isomers

Answer 12

ionization and hydration

Question 13

ionization isomers

Answer 13

exchange ligands between inner and outer coordination spheres

Question 14

Coordination isomers

Answer 14

ligands swap between two complex ions. Applies only to salts of coordination complexes where cation and anion are both complex ions. All or some ligands swap.

Question 15

ambidentate

Answer 15

can coordinate through different donors/bases

Question 16

linkage isomers

Answer 16

occur in complexes where ligand is ambidentate
