Abstract

The syntheses of five new 1-chloro-3-aryl-5-trichloromethyl-1λ4,2,4,6-thiatriazines, aryl = 4-R-C6H4- (R = CH3O, CH3, H, Cl and CF3), are reported with full characterization. Single-crystal X-ray diffraction structure determinations on all, as well as the 5-CF3 analogue which also has R = CF3, with models produced by Hirshfeld atom refinement, produced high-accuracy structures. All six exemplars form lateral dimers with short contacts that define a centrosymmetric {δ+S···Nδ−}2 motif, with interaction distances from 3.0473(9) to 3.422(3) Å, which do not vary in an expected manner with R. Normal population analysis charges computed by B3LYP-D3/6-311++G(d,p) DFT methods show small variations, and entirely as expected from the inductive effects of R. Gas-phase minimization of the dimers with M06-2X/aug-cc-pVDZ or B3LYP-D3/6-311++G(d,p) methods, with full counterpoise correction, replicate the experimental geometries for the 5-CF3, the 5-CCl3/CH3OC6H4 and the 5-CCl3/CH3C6H4 experimental structures, but diverge for other CCl3 exemplars. Interaction energies are more than double those computed for [(HC)2N2S]2. Using a geometry-optimized model with H in place of CX3, the interaction energy reduces to a very realistic –22 to –24 kJ/mol for just the {δ+S···Nδ−}2 motif, suggesting that CX3 interactions contribute 21% (CF3) to 37% (CCl3) of the total.

    • 31a HAR was employed using NoSpherA2 (ref. 24) within Olex2 1.5-alpha on all six structures (Section 3 of the Supporting Information). The first five refined extremely well, but 4e proved challenging due to borderline data quality (twinning and disorder). Nevertheless, all the HAR models represent improvements on the precision of refinements (mean 32.3% improvement on average C–C distances; see Table S5) compared to exactly parallel models in the independent atom model (IAM). For details, see the Experimental and Table S5 in the Supporting Information. The most obvious feature of the HAR, clearly visible in Figure 3, are the full positional and anisotropic positional refinements of the hydrogen atoms (except for the C10H3 methyl group in 4b, which is rotationally disordered). Still, even such a disorder would have been difficult to pick out in an IAM model, further validating the impressive performance of NoSpherA2 (refs. 25–28). Full details on the SC-XRD structures and refinement are provided in the Supporting Information.

  • 40 A reviewer suggested investigating these interactions by the Quantum Theory of Atoms in Molecules approach. We therefore took the CC-optimized geometry at the B3LYP-D3/6-311++G(d,p) level of theory of 4c into AIMAll for an AIM analysis (ref. 41). This calculation confirmed the presence of (3,−1) critical points, usually taken as indicative of the presence of ‘bonds’, for both the (S···N) and (CCl3···S) type contacts (corresponding to the dashed lines in Figure 4) with average ∇2ρ of 0.035 a.u. for the first and 0.016 a.u. for the second type, corresponding to ‘bond’ strengths of 8.7 and 2.8 kJ/mol, respectively. So yes, BCPs exist in these optimized lateral dimers. It would, however, take a systematic comparison of these BCP energetics with those at the crystallographic geometries to be able to provide an adequate interpretation of their meanings. If anything, these preliminary results substantiate the importance of dispersion in the contributions of the chloro groups to the intermolecular interactions, since the (CCl3···N) component is shown to contribute almost 40% of the total energy (see the remaining text), exceeding this AIM estimate of 24% in the absence of dispersion.

  • 42 In ref. 2, Scheiner computes interaction energies for hypothetical selenazole dimers, where the CH moieties in the rings are replaced sequentially by one or two nitrogen atoms. It is claimed that for each additional N atom, the interaction energy almost doubles in magnitude. Of course, there is no way to test this experimentally, but our result of a higher interaction energy in the C2N3S thiatriazine fits to this prediction.
