Novel poly[Mn(H 2 O)(dmb)(muco)] ( 1 ) (H 2 muco = trans , trans ‐muconic acid; dmb = 5,5′‐dimethyl‐2,2′‐bipyridine) was obtained by self‐assembly, one‐pot, solution reaction. 1 crystallizes in a monoclinic system with P 2 1 space group and forms an infinite one‐dimensional (1D) polymer. Remarkably, the six‐coordinate Mn II display a rare distorted trigonal prismatic configuration. This unusual coordination arrangement appears to be acquired due to the supramolecular interactions of the polymeric structure of 1 , mainly throughout hydrogen bonding, giving rise to a 2D framework. Magnetic properties measurements reveal that 1 possesses weak antiferromagnetic interactions with θ (C–W) = –1.0 K and J = 458 cm –1 .
