Dinitrogen dioksida adalah sebuah senyawa anorganik dengan rumus molekul N2O2. Banyak isomer struktural yang mungkin. Pola ikatan kovalen O=N–N=O (dimer non-siklik dari nitrogen monoksida (NO)) diprediksi menjadi isomer yang paling stabil berdasarkan perhitungan ab initio dan merupakan satu-satunya yang telah diproduksi secara eksperimental.[1] Dalam bentuk padat, molekulnya memiliki simetri C2v: seluruh strukturnya planar, dengan dua atom oksigen cis melintasi ikatan N–N. Jarak O–N adalah 1,15 Å, jarak N–N adalah 2,33 Å, dan sudut O=N–N adalah 95°.[2]
