Abstract

The crystal structure of the donor-acceptor adduct (CH₃)₂HN-SO₂ is reported. Crystals of the compound are clear prisms, space group Pna2₁; at -96°C, a = 9.894(1), b = 6.051(2), c = 16.478(3) Å, D = 1.469 g/cm³, V = 786.6(5) Å³, Z = 8. The unit cell contains two crystallographically independent adducts, with N-S bond lengths of 2.015(3) Å and 1.991(3) Å. The average value, 2.00(1) Å is 0.33(4) Å shorter than the 2.34(3) Å value previously determined from microwave spectroscopy of the gas phase species, revealing a large medium effect on the length of the donor-acceptor bond. The structural results are compared with published data for the trimethylamine-SO₂ adduct, and discussed in terms of existing experimental and theoretical results for other donor-acceptor systems.
