Chiral Mn complex

The chiral Mn complex below undergoes racemization according to the equation shown. 

More recently. Hupp and Nguyen used salen-based chiral Mn-complex as a chiral linker to generate chiral MOPM through pillaring with Zn-carboxylate paddlewheel [54], Bu et al. also employed the same sbategy to consbuct several homochiral open-framework materials using homochiral camphoric acid as a rigid linker [55].
