Cr. Ross et al., Anhydrous ammonioguanidinium(2+) and dihydrated bis[aminoguanidinium(1+)] hexafluorosilicates: new co-products of preparing ferroelectric ammonioguanidinium(2+) hexafluorozirconate (vol 55, pg 626, 1999), ACT CRYST B, 55, 1999, pp. 626-626
An error in printing is reported. In the paper by Ross et al [Acta Cryst. (
1999), B55, 246-254] the length of a bond formed by H3 is given incorrectly
in the sixth sentence of the first paragraph of 3.3 on page 251. The sente
nce should read 'The out-of-plane displacement modifies the hydrogen-bondin
g pattern, allowing an approach of 2.21 (2) Angstrom to F2, see Table 4; th
e resulting increase in structural stability supports this model.'.
