Solvothermal Construction of a Coordination Polymer around in Situ Generated Pyroglutamic Acid: Preparation, Crystal Structure, and Magnetic Behavior of [Mn(C5H6NO3)(2)](infinity) In situ solvothermal dehydration of glutamic acid followed by coordination to Mn(II) leads to formation of an infinite chain, the magnetic behavior of which has been measured and modeled.
