What are physical important characteristics of coordinate compounds?

The physical important characteristics for coordinate compounds are:
(i) Physical state: They may be gaseous, liquids or solids.
(ii) Melting and boiling points: They generally have low melting and boiling points. However, their melting and boiling points are relatively more than the covalent compounds.
(iii) Conductivity: Generally, they are poor conductors of electricity but some of them are good conductors also.
(iv) Solubility: Generally, they are insoluble in water but soluble in organic solvents. However, some of them are soluble in water.
(v) Isomerism: They exhibit stereoisomerism due to rigid and directional nature of the coordinate bond.
