The title compound is prepared by adding aqueous ammonia to a solution of phosphoric acid containing a small amount of iron (III) ions (3%). It crystallizes in the monoclinic system, space group C2/c, a ؍ 16.8450(9) A > , b ؍ 9.6111(1) A > , c ؍ 17.6470(7) A > , and ؍ 90.91(2)°, R ؍ 0.031,
Raman spectra of a single crystal K2H2C4O4\*2Hz0 and of polycrystalline K2H2C404.2H20, K2H2C4O4.2Dz0, and K2H2C404 have been recorded at room temperature from 10 to 3500 em-'; Raman and infrared data are compared. The existence of hydrogen bond =CH \* --0 is confirmed. ## Groupe Groupe Groupe mol
