The unlikely role of nitrogen in NH3 as an electron accepting pnicogen has been observed experimentally using matrix isolation infrared spectroscopy and computationally. Nitrogen hosts twin H-N...Cl pnicogen bonds, which enhance the stabilization of a dominantly Cl-P...N phosphorus bonded PCl3-NH3 heterodimer. The Cl-P...N phosphorus bond is proven to operate via the prominent sigma-holes of phosphorus whilst the H-N...Cl pnicogen bonds appear to be driven by dispersion. The possibility of nitrogen in NH3, a popular Lewis base, acting as an electron acceptor, reveals a thus far unexpected scenario: pnicogen bonds operating even in the absence of sigma/pi-holes.
