Abstract

C15H22N204.H20 , Mr= 312.37, monoclinic,P21, a=5.577(2), b=8.686(2), c= 16.228 (2) A,fl=92.63(2) ° , V=785(1)A 3, Z=2, O =1.34,Dx= 1.32Mgm -3, CuKa, 2= 1.54184'~, /2=0.78 mm -I, F(000) = 320, T= 293 K. The final R value for 1607 observed reflections ll,,>_3tr(l,,)l is 0.039. The terminal N 1 is protonated and the dipeptide exists as a zwitterion. The crystal structure is stabilized by extensive hydrogen-bonding interactions involving N and O atoms, with N...O in the range 2.65 (1)-2.95 (1) ,/~ and O...O in the range 2.60 (1)-2.78 (1) A.
