synthesis and structure of 2-amino-1,1-difluorophosphonic acid (3) are described, providing the first X-ray crystal structure determination of a difluoromethylenephosphonatemoiety; the structure allows an isosteric comparison to be drawn between the phosphate C–O–P bond angle and the phosphonate C–CF2–P and C–CH2–P bond angles with particular reference to the use of phosphonates as phosphatemimics in biological
