Resumen:
Structural, conformational, and configurational properties of the gaseous molecule ((fluoroformyl)imido)sulfuryl difluoride, FC(O)N=S(O)F2, have been studied by vibrational spectroscopy (IR (gas) and Raman (liquid)) and quantum chemical calculations (HF, MP2, and B3LYP with 6-31+G* and 6-311+G* basis sets); in addition, the solid-state structure has been determined by X-ray crystallography. FC(O)N=S(O)F2 exists in the gas phase as a mixture of a favored antiperiplanar-synperiplanar form (the SdO double bond antiperiplanar with respect to the C-N single bond, and the C=O group synperiplanar with respect to the S=N double bond) in equilibrium with less abundant antiperiplanar-antiperiplanar, synclinal-synperiplanar, and synclinal-antiperiplanar structures. The crystalline solid at 163 K (monoclinic, P21/c, a ) 5.1323(7) Å, b ) 15.942(2) Å, c ) 16.798(2) Å, â ) 95.974(3)°, Z ) 12) consists of three similar antiperiplanar-synperiplanar forms.
