Cytosine monohydrate
WebFeb 1, 2014 · The crystal structure of cytosine (Barker & Marsh, 1964) and cytosine monohydrate (Jeffrey & Kinoshita, 1963) were determined many years ago. Many inorganic cytosinium salts have been synthesized, including the hydrochloride (Mandel, 1977) and the dihydrogenmonophosphate (Bagieu-Beucher, 1990) salts. WebThe distances and angles of the cytosine moiety of the molecule do not compare well with those found in cytosine monohydrate and cytidine. The discrepancies are attributed to the influence of hydrogen bonding on the double bond character of the carbonyl bond C*(2)-O*(2) and on the influence of the N 4 a axis which are held together by van der ...
