“…In addition, two crystal structure determinations of co-crystals containing C6 are also known [18,19]. In comparison a complete set of crystal structures of the corresponding saturated carboxylic acids (propionic acid to pentadecanoic acid) is available from the literature [20][21][22][23][24]. In this contribution, we report on the synthesis, characterization and crystal structure determinations of two members of the series of α,β-unsaturated carboxylic acids: (E)-non-2-enoic acid (C9) and (E)-dec-2-enoic acid (C10), respectively, which are linked into centrosymmetric dimers via pairs of O-H···O hydrogen bonds in the crystals.…”

“…It is worth noting that also in the structure of propionic acid (Strieter, Templeton, Scheuerman & Sass, 1962) the methyl group lies in the molecular plane. Since the space group introduces a twofold axis along the molecular length the methyl group must on average occur on both sides of this axis but with half weight.…”

The room-temperature crystal structure of dicalcium barium propionate, Ca2Ba(C2H5COO)6, is described. It is cubic with a = 18.178 (1)/k and space group The propionate molecules are found to be disordered between two sites. It is suggested that there are large-amplitude oscillations of the molecules about pseudo-twofold axes with occasional flipping of the methyl C atoms from one site to the other. Diffusescattering studies indicate correlations along (110) between the propionate groups with smaller correlations along (001). These are explained by an examination of the intermolecular contacts of the methyl C atoms, which shows that it is impossible to construct a fully three-dimensionally ordered structure.

“…Such overcorrection has been noted earlier for a methyl group undergoing a very large amplitude of vibration about its threefold axis (Sequeira, Berkebile & Hamilton, 1968).

O distances of 2.62-2.645 A were found. The structures of these acids take the form of hydrogen bonded dimers, in contrast with the infinite hydrogen bonded chains in the present structure.…”
