Structure edit
I believe the structure of PhAsO currently shown in the article is misleading. Thanks to the double bond rule, species with As-O single bonds are much more stable. The crystal structure of a cyclic tetramer of PhAsO has been reported, alongside structures of some of its complexes with transition metals: I. M. Müller, J. Mühle, Z. anorg. allg. Chem. 1999 625, 336-340 (DOI: 10.1002/(SICI)1521-3749(199902)625:2<336::AID-ZAAC336>3.0.CO;2-6).

- Greenwood and Earnshaw confirms that arsonous anhydrides (as they're apparently called), RAsO, are all polymeric and do not contain As=O double bonds.[1] --Ben (talk) 11:38, 29 April 2016 (UTC)
