(4-Nitrophenolato)(subphthalocyaninato)boron(III)1

The main feature of the structure of the title compound, C30H16BN7O3 or NO2PhO-BsubPc, are pairs of molecules linked through π-interactions between the concave faces of the BsubPc fragments at a distance of 3.5430 (11) Å across an inversion centre. However, the angle between the planes of the five- and six-menbered rings involved in this interaction is 1.44 (10)°, causing the interacting BsubPcs units to be slightly askew rather than parallel as is typical for π-stacking interactions.
