Abstract

The crystal structure of the title compound, [Ni₃(C₈H₄O₄)₃(C₃H₇NO)₄], is a two-dimensional coordination network formed by trinuclear linear Ni₃(tp)₃(DMF)₄ units (tp = terephthalate = benzene-1,4-di-carboxyl-ate and DMF = di-methyl-formamide) displaying a characteristic coordination mode of acetate groups in polynuclear metal-organic compounds. Individual trinuclear units are connected through tp anions in a triangular network that forms layers. One of the DMF ligands points outwards and provides inter-actions with equivalent planes above and below, leaving the second ligand in a structural void much larger than the DMF mol-ecule, which shows positional disorder. Parallel planes are connected mainly through weak C-H⋯O, H⋯H and H⋯C inter-actions between DMF mol-ecules, as shown by Hirshfeld surface analysis.

Keywords: Ni metal-organic coordination network; crystal structure; layered structure; terephthalate.
