Question
Explain homoleptic and heteroleptic complexes with examples.
✓
Answer
$1.$ Homoleptic complexes:The complexes in which metal ion is bound to only one type of ligands are called homoleptic complexes.
e.g. In $[Co(NH_3)_6]^{3+},$ only one type of ligand, $NH_3$ surrounds the $Co^{3+}$ ion.
$2.$ Heteroleptic complexes: The complexes in which metal ion is surrounded by more than one type of ligands are called heteroleptic complexes.
e.g. In complex $[Co(NH_3)_4Cl_2]^+,$ there are two types of ligands, $NH_3$ and $Cl$ attached to $Co^{3+}$ ion.
$3.$ Double Salt:Double salts are ionic substances created by combining two distinct salt compounds. In aqueous media, double salts totally dissociate.
eg. $FeSO_4 (NH_4) _2SO_4 · 6H_2O ($Mohr's salt$).$
