Why is the chemical structure of water shown as H2O rather than H-O-H with the bonds making a 104.45 degree angle? For water only, the molecular formula is shown rather than the chemical structure. To make matters worse, exporting this to SYMYX draw gives the chemical structure as OH2. Is is possible to correct this inconsistency? Thanks!

Thank you for your feedback. In response to your question; the ChemSpider database is not intended to provide the data that you describe. ChemSpider is based upon chemical structures and captures the key information that distinguishes molecule, Atom-connectivity and stereochemical data (E/Z, R/S). Our data is not intended to convey information on conformation or accurate bond angles. With regards to the depiction of H2O, OH2 or H-O-H, each of these depictions is valid chemical description of a molecule of water and may be considered consistent for the purposes of identifying that the molecule in question is water.
