Crystal structure and Hirshfeld surface analysis of poly[tris­(μ(4)-benzene-1,4-di­carboxyl­ato)tetra­kis­(di­methyl­formamide)­trinickel(II)]: a two-dimensional coordination network

The crystal structure of the title compound, [Ni(3)(C(8)H(4)O(4))(3)(C(3)H(7)NO)(4)], is a two-dimensional coordination network formed by trinuclear linear Ni(3)(tp)(3)(DMF)(4) units (tp = terephthalate = benzene-1,4-di­carboxyl­ate and DMF = di­methyl­formamide) 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 inter­actions with equivalent planes above and below, leaving the second ligand in a structural void much larger than the DMF mol­ecule, which shows positional disorder. Parallel planes are connected mainly through weak C—H⋯O, H⋯H and H⋯C inter­actions between DMF mol­ecules, as shown by Hirshfeld surface analysis.
