    • note
    • Note that any extra entropy of melting for MeO-mHB, due to the freeing of torsional degrees of freedom of the methoxyl group, must tend to lower its melting point. Of course, analyzing melting points in terms of group interactions has only qualitative significance, since melting points compare solids with the corresponding liquids, not with gas-phase molecules. Although liquids should be less able to optimize intermolecular attractions than solids, they do not eliminate them.

    • To measure ribbon width the nonhydrogen atoms are projected on the plane analogous to (100) of mHB. The most remote atom, which defines the edge of the ribbon, is C(10). In Br-mHB, it is O(2).

    • O⋯O distances: 2.86, 3.02, 2.86 Å. C-O⋯O angles: 136°, 144°, 107°. C-C-O⋯O torsional angles: -76°, 103°, -87°. Note that a symmetry dyad of the C2/c space group passes through the middle of the C-shaped chain, meaning that the chain could change its polarity by rotation of the four OH groups. The H-atoms are almost certainly disordered, perhaps dynamically.

    • For example, 11-bromoundecanoyl peroxide melts 20°C higher than isomorphous 11-bromoundecanoyl dodecanoyl peroxide (72.3-75.7°C vs 53 0-53.8°C); even-numbered α,ω-dibromoalkanes melt 20-50°C higher than their dimethyl analogues. There are many counter examples, such as the odd-numbered α,ω-dibromoalkanes, where the melting points differ by only a few degrees. See: Breusch, F. L. Fort. Chem. Forsch. 1969, 12, 119 and ref 3c.
