shapes of complex ions Flashcards
what is the bond angle in octahedral complexes
90 degrees
what 2 types of isomerism can octahedral complexes have
cis trans
(geometric isomerism)
optical isomerism
(stereoisomerism
define cis isomers in complexes
different ligands are next to each other
define trans isomers in complexes
different ligands are opposite each other
what type of ligands can optical isomers occur in
multidentate or bidentate ligands
what type of ligands are octahedral complexes typically formed from
smaller ligands
( H20, NH3)
what type of ligands are tetrahedral complexes typically formed from
larger ligands (Cl-)
what is the bond angle in a tetrahedral complex
109.5
what is the bond angle in a square planar complex
90 degrees
what type of isomers can be formed from square planar complexes
cis - trans isomers
what is the formula for cis platin
[Pt (NH3)2 Cl2]
what is the use of cisplatin
an important drug that fights cancer (chemotherapy)
what is the bond angle in linear complexes
180
what example of a linear complex do you need to know
[Ag(NH3)2]+
linear complex formed in tollens reagent
Ammonical silver nitrate
explain the shape of Haem B
this is an iron (II) complex with a multidentate ligand
oxygen forms a coordinate bond with the Fe2+ ion
haemoglobin allows oxygen to be transported around the blood
