The crystal structure of the trans-dtmer of 2,6-di-isopropylnitrosobenzene has been established by X-ray diffraction studies. The crystals are monoclinic, space group P21/n, with Z = 2 and unit-cell constants a = 8.585 4(10), b = 10.9497(11), c= 12.1135(14) Å, and ß= 94.27(1)°. The N-0 and C-N bond distances are normal for aromatic dimeric nitroso compounds but the N-N distance is significantly longer than in most trans-dmers due to unavoidable intramolecular steric interactions between isopropyl groups in opposite halves of the dimer.
