The deformation electron density has been studied in LiOH.H 2O at 295K using a combination of X-ray and neutron diffraction data. Notoriously high extinction was present in the neutron data. Despite an attempt to reduce this by shock-cooling, the subsequent refinement of an extinction correction met with only partial success. Limited use was thus made of the neutron data in the determination of static multipole deformation density maps. The resulting peak maximum in the O-H bonds of the water molecule is 0.66 e Aring -3, and of the OH - ion 0.49 e Aring -3. Lower peaks are observed in the lone-pair regions: 0.22 e Aring -3 for H 2O and 0.27 e Aring -3 for OH -. These are to be compared with the results of theoretical ab initio calculations given by Hermansson and Lunnell (1982).
