Complexes in which a metal is bound to more than one kind of donor groups are known as _________complexes.

In general, ligands can be arranged in a series in the order of increasing field strength. This series is termed as ______________ series.

_________ theory is an electrostatic model which considers the metal- ligand bond to be ionic arising purely from electrostatic interactions between the metal ion and the ligand.

When a di- or polydentate ligand uses its two or more donor atoms to bind a single metal ion, it is said to be a _________ligand.

Ligands which can ligate through two different atoms is called __________ ligands.

Complexes containing free unpaired electrons are said to be __________ in nature.

___________isomers have the same chemical formula and chemical bonds but they have different spacial arrangement.

_____________ isomerism arises in a co-ordination compound containing ambidentate ligand.

Ligands which can ligate through two different atoms is called __________ ligands.

______________isomerism erases from the different positions of H₂O molecules inside and outside the coordination sphere of the same central ion.
