The low proton conductivity of proton-conducting solids at reduced relative humidity (RH) hinders the performance of fuel cells. Even though various proton conducting frameworks have been developed, the conductivity of such methods dropped due to weak host–guest interactions of complex synthesis process, posing significant damage in increasing temperatures, limited practical use owing to the high costs. Therefore, the development of new and inexpensive proton-conducting materials with excellent performance has been the subject of intensive research. Hence, in this paper, an environmentally benign coordination polymer called Manganese-based proton conducting material that possesses the structural architectures as those of the other proton conducting metal-organic framework (MOF) and Coordination Polymers (CP) is presented. In order to aid the electrochemical characteristics of the compound
