Spectroscopic and Structural Studies of Difluorophosphoryl Azide F2P(O)N3, Difluorophosphoryl Isocyanate F2P(O)NCO, and Difluorophosphoric Acid Anhydride, F2(O)POP(O)F2

“…The lengths of the P1−O1 and P1−O2 bonds, 1.4312(12) Å and 1.5652(6) Å, respectively, are close to the average PO double (1.440(1) Å) and P−O single bond lengths (1.570(4) Å) in o ′-(P 2 O 5 ) ∞ , and the angle at the bridging oxygen atom (O2) in F 2 (O)POP(O)F 2 (140.89(10)°) is similar to that in o ′-(P 2 O 5 ) ∞ (143.7(2)°) as well . The molecular structure of F 2 (O)POP(O)F 2 is compared with that of solid disulfuryl difluoride, FS(O) 2 OS(O) 2 F . In the solid FS(O) 2 OS(O) 2 F, the two FSO 2 groups are staggered by ϕ(FS−SF) of 144.97(5)°, and an SOS angle of 123.44(7)° was found at the bridging oxygen atom.…”

Disulfuryl Dichloride ClSO2OSO2Cl: A Conformation and Polymorphism Chameleon

“…In comparison to the gas‐phase structure of ClSO 2 OSO 2 Cl the dihedral angle (80.5(4)°) lies within the range of the solid‐state parameter. Note that the related disulfuryl difluoride, FSO 2 OSO 2 F, adopts C 2 symmetry in the solid state. Its central S−O bonds at 1.610(1) Å are shorter by about 0.01 Å than the shortest measured here in the chlorine analogue.…”

“…The range for the SÀCl bonds is 1.966(1) to 1.979(1) .T he centralS 1-O1-S2 angle varies from 123.9(1)8 to 125.0(1)8.T he dihedral angles f(Cl1-S1-O1-S2) and f(Cl2-S2-O1-S1) adopt values between 86.0(1)8 and 77.2(1)8.T he mean value is in good agreementw ith the calculated minimum structure adopting ad ihedral angle of 78.88 at the MP2/cc-pVTZ level of theory.I nc omparison to the gas-phase structure of ClSO 2 OSO 2 Cl the dihedral angle (80.5(4)8) lies within the range of the solid-state parameter. Note that the related disulfuryl difluoride, FSO 2 OSO 2 F, [8] adopts C 2 symmetry in the solid state. Its central SÀOb onds at 1.610 (1) are shorterb y about 0.01 than the shortest measured here in the chlorine analogue.…”

“…Aprevious study on the photochemicalpropertieso fdisulfuryld ichloride [4] revealed its high thermal and photochemical stability.A lthough the title compound is known for more than ac entury [5] no complete elucidation of its spectroscopic or structuralf eatures was undertaken. [8] In the gas phase the difluoride solely consists of an anti-conformer with at orsional angle f(FS···SF) of 119.1(6)8,w hereas in the solid state this torsional angle measures 144.

“…Although the title compound is known for more than a century no complete elucidation of its spectroscopic or structural features was undertaken. Contrary to that, the corresponding disulfuryl difluoride, FSO 2 OSO 2 F, has been characterized spectroscopically and structurally—first in the gas phase and later also in the solid state . In the gas phase the difluoride solely consists of an anti ‐conformer with a torsional angle φ (FS⋅⋅⋅SF) of 119.1(6)°, whereas in the solid state this torsional angle measures 144.9(1)° while no pronounced individual interactions amongst the molecules can be identified.…”
