| New oligomeric analogues of poly(sulfur nitride), i.e. 3-ClC6R4XN=S=NXC6R4Cl-3 (58; R = H, F and X = S, Se), were synthesized and structurally characterized in the solid state by single-crystal XRD, in solution by variable-temperature NMR spectroscopy and in the gas phase with DFT/B3LYP calculations. In the crystal, compounds 57 display the well-known Z,Z configuration, whereas 8 (R = F, X = Se) is the first compound to display the E,Z configuration amongst twelve structurally defined ArXN=S=NXAr (X = S, Se) derivatives in the hydrocarbon and fluorocarbon series. Through a careful analysis of the packing schemes and the intermolecular interactions of the various compounds, an explanation of the abnormal behaviour of 8 is put forward. |
