Figure 6

Molecular structures of [6 a][OTf]⋅HOTf (left) and [6 b][OTf] (right). Thermal ellipsoids pictured at 50 % probability level; HOTf/OTf− and hydrogen atoms, with the exception of those bonded to N1, omitted for clarity. There are two crystallographically independent molecules of 6 b in the lattice, for clarity, only bond metric data for one of them is provided. Selected interatomic distances [Å] and angles [°]; 6 a: P1−N1 1.926(2), P1−O1 1.615(2), P1−O2 1.619(2), N1−C6 1.478(3), N1−C20 1.470(3), N1−H1 0.85(3), O1‐P1‐O2 104.80(10), N1‐P1‐O1 90.16(8), N1‐P1‐O2 104.80(10), C6‐N1‐C20 112.46(17), C6‐N1‐H1 114(2), C6‐N1‐P1 105.39(14), C20‐N1‐H1 111(2), C20‐N1‐P1 105.20(13), H1‐N1‐P1 108(2). 6 b: As1−N1 2.028(2), As1−O1 1.791(1), As1−O2 1.810(1), N1−C6 1.472(2), N1−C20 1.466(2), N1−H1 0.82(2), O1‐As1‐O2 98.55(5), N1‐As1‐O1 87.00(5), N1‐As1‐O2 85.69(5), C6‐N1‐C20 114.51(11), C6‐N1‐H1 109.3(13), C6‐N1‐As1 105.16(9), C20‐N1‐H1 111.3(14), C20‐N1‐As1 105.87(8), H1‐N1‐As1 110.5(14).
