Wherever I have referred, it puts me in a dilemma about the exact differences between these. It would be really helpful if someone can put me out of this trouble.
Hi Srividya, these materials have different compositions and bonding, for example, CPs are porous crystalline materials made of metal ions or clusters connected by organic ligands through coordination bonds. MOFs are the subclass of CPs, with similar composition and bonding, CPs and MOFs are hybrid materials. While MCOFs are the combination of MOFs and COFs (made of organic ligands linked by strong covalent bonds containing nonmetal elements such as hydrogen, carbon, boron, nitrogen, and oxygen). Following article might be useful for you.

Coordination polymers, Metal-Organic Frameworks (MOFs), and Metal-Organic Covalent Frameworks (MCOFs) are all materials featuring metal ions coordinated to organic ligands but differ in structure and application. Coordination polymers form infinite one-, two-, or three-dimensional networks with flexible designs. MOFs, a subset of coordination polymers, have highly ordered, porous structures ideal for gas storage, separation, and catalysis due to their tunable pore sizes and high surface areas. MCOFs combine the structural robustness of MOFs with covalent bonding, offering enhanced chemical stability and diverse functionality for similar applications.
- Coordination polymers are extended structures formed by the coordination bonds between metal ions and organic ligands. They can be one-dimensional (chains), two-dimensional (layers), or three-dimensional (networks) depending on how the metal ions and ligands connect.
- MOFs are a subset of coordination polymers characterized by a highly ordered, crystalline, and often porous structure. They are formed by the coordination of metal ions or clusters with organic ligands, resulting in a three-dimensional framework.
- MCOFs are a more recent development and can be considered a subcategory of MOFs. The term MCOF generally refers to frameworks that are specifically designed with certain organic functionalities coordinated with metals to achieve specific properties or functions.
