A biological process involved in the reduction of this element uses an iron-molybdenum complex, while carbon is double bonded to this element in imines, and single bonded to it in amines.
One atom of this element is found in rings called lactams, where it is bound to two carbons on the ring. A compound containing two atoms of it and four of hydrogen is synthesized in the Olin-Raschig process.
