I build from text `O-N+O`, I delete the hydrogen atom added automatically on N, then I click Ctrl+M. Both the bond length and the angle differ from what I see in the top right image here: https://en.wikipedia.org/wiki/Nitrogen_dioxide |

And regarding nitrite, which is ONO- Why doesn't it show it to me as having a resonance structure? How would I tell Chem3D to build it with a resonance structure instead of O=N-O- |

The bond angle on Nitrite is supposedly around 115° (source: https://en.wikipedia.org/wiki/Nitrite#Structure) Minimizing with Chem3D gives me 121° |
