Microwave rotational spectra for the complexes HCCH-HCN, HCCH-DCN, DCCD-HCN, H2CCh2-HCN and H2CCH2-DCN were observed using a pulsed nozzle Fourier transform spectrometer. The distance from the HCN carbon atom the the center of mass is. 3.655(10) Å for acetylene-HCN and 3.709(10) Å for ethylene-HCN. Both complex are T-shaped with the HCN hydrogen atom closest to the CC bond. The HCN axis is perpendicular to the plane of ethylene for ethylene-HCN. Nitrogen and deuterium quadrupole coupling was measured.
