✦ Synopsis

The high resolution IR spectra of HCCCN-CO 2 and HCCCN-N 2 have been studied using molecular beam optothermal spectroscopy. For both complexes, structural information has been obtained; HCCCN-CO 2 has been determined to be T-shaped with the CO 2 molecule at the N end of HCCCN, while N 2 -HCCCN was found to be hydrogenbonded in a linear configuration. Accurate molecular constants have been obtained. From the rotational constants, the van der Waals bond lengths of the two dimers have been determined assuming that the structure of the monomer units does not change upon complexation. The results are compared with those for the corresponding complexes of HCN.

The proton (H) attached to the bold structure at the nitrogen atom of the acylthiourea ligand in Scheme 2 in the printed paper [1] was present in error. These ligands are actually deprotonated, and the proton (H) has been removed in the corrected Scheme 2 shown in this document.
