Bond length is inversely proportional to bond order.

Bond order = 1/2(Nb-Na)
Nb=electrons in bonding mol. orbital
Na=electron in anti bonding mol. orbital

In case of NO and NO(-), the extra electron enters the anti bonding mol. orbital and hence the bond order decreases and bond length increases.
The quality of a person's life is in direct proportion to their commitment to excellence, regardless of their chosen field of endeavor.

It is during our darkest moments that we must focus to see the light.
