Abstract

The crystal structure of the title compound has been determined at room temperature. The crystals are monoclinic, space group P21/c, Z = 2, with a = 7.867(2), b = 5.305(1), c = 12.574(2) Å and β = 72.73(2)°. The structure was refined to R = 0.042 for 589 observed reflections. The molecule is on an inversion center. The agreement among chemical equivalent bond lengths is generally very good, thus confirming the short carbonyl distance (1.185 Å). The crystal is built of stacks of only partially overlapping NTDA molecules along b.
