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

Abstract

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
