title: Two cobalt(II) supramolecular isomers based on N,N'-bis(pyridin-3-yl)oxalamide induced by the molecular orientation of lattice DMF molecules.
abstract: Supramolecular isomerism for coordination networks refers to the existence of different architectures having the same building blocks and identical stoichiometries. For a given building block, different arrangements can lead to the formation of a series of supramolecular isomers. Two one-dimensional Co(II) coordination polymers based on N,N'-bis(pyridin-3-yl)oxalamide (BPO), both catena-poly[[[dichloridocobalt(II)]-bis[μ-N,N'-bis(pyridin-3-yl)oxalamide-κ(2)N:N']] dimethylformamide disolvate], {[CoCl2(C12H10N4O2)2]·2C3H7NO}n, have been assembled by the solvothermal method. Single-crystal X-ray diffraction analyses reveal that the two compounds are supramolecular isomers, the isomerism being induced by the orientation of the dimethylformamide (DMF) molecules in the crystal lattice.
