Coordination complexes
a ligand and a metal center that can act as a cation or an anion in a compound depending on if it has a positive or negative charge
Coordination compounds
complex or contain complex ions
What is the order of the stuff that you name in a coordination complex (hint: three things)
1- name the ligand alphabetically without the prefixes
2-name the metal
3-name the oxidation state of the metal
How do the ligand names change when they act as anions?
- when they normally end in ide, they will end in o
- when they normally end in ite or ate, they will end in ito and ato
Which is cyano and which is isocyano
cyano = CN-, isocyano = NC-
Which is nitro and which is nitrito?
nitro = NO2-, nitrito = ONO-
Which is thiocyanato and which is isothyiocyanato?
SCN- is the regular one and NCS is iso
What is the composition of the ion thiosulfato?
S2O3 2-
Do the name of a ligands change if they are neutral?
no

What are polydentate ligands?
en, ox2-, and EDTA4-
en
ethylenediamine
ox2-
oxalato
EDTA4-

What are the rules for ligand multiplicity?
use the mono, di, tri, etc system for monodentate ligands, and bis, tris, and tetrakis prefized when using polydentate ligands that already have a prefix
[CrCl2(H2O)4]+
tetraaquadichlorochromiun(III) ion
[CoCl2(en)2]+
chloroethylenediaminecobalt(III) ion
Which metals have weird names when you put them in an anion?
iron, copper, tin, silver, lead, gold
iron in an anion
ferrate
copper in an anion
cuperate
tin in an anion
stannate
silver in an anion
argenate
lead
plumbate

what do you write at the end of a compound if it is an ion
Ion
[Cr(OH)4]-
tetrahydroxochromate(III) ion
[CoCl(NO2)(NH3)4]+
