The accurate X-ray single-crystal structures of the isoflavone compounds 4-O-methylalpinumisoflavone, O,O-dimethylalpinumisoflavone and 5-O-methyl-4-O-(3-methylbut-2-en-1-yl)alpinumisoflavone {alpinumisoflavone = 5-hydroxy-7-(4-hydroxyphenyl)-2,2-dimethyl-2H,6H-benzo[1,2-b:5,4-b']dipyran-6-one} from data sets measured at cryogenic temperature have been obtained from invariom modelling using theoretically predicted Hansen and Coppens multipole-model form factors, which describe the aspherical electron density distribution. Molecular dipole moments and electrostatic potentials obtained from invariom modelling are discussed and compared with results from ab initio theoretical calculations. All three studied compounds are solvent extracts of root bark or seed powder of Millettia thonningii (leguminosae), a plant molluscicide and cercaricide used in Franco West Africa as medication against various diseases. The compounds' toxicities to brine shrimp have been determined and their different potencies tentatively related to conformation differences, intramolecular contacts, dipole moments and electrostatic potential features.

Geometry. The positions of the H atoms atoms were freely refined using invariom database pseudoatom parameters up to hexadecapoles. This procedure yields bond distances in better agreement with standard neutron results.

As local atomic site symmetry was employed for the multipole parameters, a local atomic coordinate system was necessary for ensuring the correct orientation of the aspherical electron density. Dummy atoms were therefore necessary in some cases.

Geometry. The positions of the H atoms atoms were freely refined using invariom database pseudoatom parameters up to hexadecapoles. This procedure yields bond distances in better agreement with standard neutron results.

As local atomic site symmetry was employed for the multipole parameters, a local atomic coordinate system was necessary for ensuring the correct orientation of the aspherical electron density. Dummy atoms were therefore necessary in some cases.

Special details top

Geometry. The positions of the H atoms atoms were freely refined using invariom database pseudoatom parameters up to hexadecapoles. This procedure yields bond distances in better agreement with standard neutron results.

As local atomic site symmetry was employed for the multipole parameters, a local atomic coordinate system was necessary for ensuring the correct orientation of the aspherical electron density. Dummy atoms were therefore necessary in some cases.

The coordinates of atom O(1 A) were kept fixed to provide an origin for the space group.
