Coordinating solvent

WebThere are a number of physical properties of a solvent that are of great importance in determining its behavior and in fact its usefulness as a solvent. These are : 1. The temperature range over which it is a liquid, i.e. liquid range 2. Dielectric constant 3. Donor and acceptor properties, i.e., its Lewis acid base behavior 4. WebOct 4, 2024 · Figure 14.6. 1: Formation of a Lewis acid-base complex. An example of a coordination complex is hexaaquo cobalt dichloride, Co (H 2 O) 6 Cl 2. This compound contains a Co 2+ ion. This electrophilic metal ion is coordinated by six nucleophilic water ligands. Because the water molecules are neutral, the complex still has a 2+ charge overall.
