Results of quantum-mechanical calculations (Dunitz and Orgel, 1957) have given values for the OSPEs of a number of transitional metal ions and the degree of inversion of mixed spinels...

Wallis and Dunitz (1984a) also investigated another type of sterically induced interaction of a donor group with a diazonio group. Quinoline-8-diazonium-l-oxide tetrafluoroborate (4.14) was analyzed at 95 K (R = 0.034). 

Fig. 4-1. Distances (pm) and angles (°) relevant to the 0(1) N(l) = N(2) interaction in the quino-line-8-diazonium-l-oxide ion 4.14 (after Wallis and Dunitz, 1984 a).

The structure of 1,2,3-benzoxadiazole (4.16) bears some resemblance to Wallis and Dunitz s structure (4.14, Fig. 4-1) for quinoline-8-diazonium-l-oxide, as the latter structure has a tendency towards forming a five-membered heteroaromatic ring. The two compounds are, however, different with respect to the involvement of an N(2) and an N(l) diazo atom. The 1,2,3-benzoxadiazole structure is consistent with the bands observed in the 9.45 to 12.37 eV range in the photoelectron spectrum,... 

Atom numbering as in Figure 11-1.1 thank my colleague J. D. Dunitz (ETH Zurich) for providing the appropriate computer program for the calculation of these atomic distances and the various N O distances mentioned below.
