Detection of C-cyanophosphaethyne, NC–CP, by microwave spectroscopy

Abstract

The microwave spectrum of the new species C-cyanophosphaethyne NC–CP has been detected in the products of a gas phase high temperature (ca. 700 °C) reaction between cyanogen azide, NCN₃, and phosphaethyne, HCP; the new species which is the monophosphorus analogue of cyanogen, (CN)₂, has a dipole moment of 3·5 D.
