Figure 5
Comparison of the geometry of four types of (MeO)2cDHAP− ions present in the crystal of β-NH4[(MeO)2cDHAP]. Chair conformers with different orientations of the acetal groups are shown in black and grey. Skew conformers of different helicity are shown in red (SP) and blue (SM) (A, C, E and F anions from RTP, respectively). The common reference fragment is Oexo—P—Oexo. |
