Abstrakt: In this work we describe the structure of a coordination polymer, which was solved by using synchrotron X-ray powder diffraction. The heterometallic CuII–MnII compound, [Cu2Mn2(bopba)(DMSO)7]·DMSO, was assembled from a binuclear oxamato copper(ii) complex and manganese(ii) ions, generating a Mn–Cu–Mn–Cu– chain motif. Each chain is connected to two others, resulting in a folded two-dimensional coordination network where the uncoordinated DMSO molecule is located in the space between the layers. The loss of the DMSO molecules leads to the loss of both crystallinity and long range magnetic order. The knowledge of the structure allowed the quantification of the intrachain magnetic interaction.
