Synthesis and magnetic property of porous naphthalenetetracarboxylate manganese complex, the first (μ2-aqua)bis(μ2-carboxylate)-bridged manganese polymer

A manganese coordination polymer [Mn2(NTC)(H2O)2]n, where NTC is 1,4,5,8-naphthalenetetracarboxylate anion, has been synthesized by slow diffusion of manganese chloride and H4NTC. Mn(II) ions are bridged by one coordinated water and two carboxylate groups in syn–syn mode to form infinite chains, which are further cross-linked by the naphthalene spacers of the NTC to produce 3-D extended network with open-channels. An antiferromagnetic coupling interaction between adjacent manganese ions dominates the magnetic property of the compound.
