The 1:1 adduct of cobalt(II) terephthalate with N,N-dimethylformamide

Y.-L. Fu, J.-L. Ren and S. W. Ng

Abstract: The solvothermal reaction of cobalt(II) nitrate and terephthalic acid in N,N-dimethylformamide (DMF) yields the polymeric title compound, poly[cobalt(II)-₂-N,N-dimethylformamide-²O:O-₄-terephthalato- ⁴O:O':O'':O'''], [Co(C₈H₄O₄)(C₃H₇NO)]_n. In the crystal structure, both the Co atom and the terephthalate group occupy special positions of 2/m site symmetry. The DMF ligand is located on a mirror plane with the N atom on a special position of site symmetry mm2. The octahedral coordination polyhedron around the Co atom has two opposite sites that are occupied by the O atoms of DMF molecules; the other sites are occupied by the carboxyl O atoms of four different terephthalate groups. The compound adopts an open framework structure having channels in which the disordered DMF molecules reside.
