Abstract

Single crystals of sarcosine barium chloride tetrahydrate were crystallised from a saturated aqueous solution containing stoichiometric amounts of sarcosine and barium chloride, in 2: 1 proportion. The intensity data were collected using a CAD‐4 diffractometer with graphite monochromated MoKα radiation. The crystal data are as follows: a = 7.235(1) Å, b = 10.668(4) Å, c = 15.686(3) Å, V = 1210.7 Å^3^, F.W. = 369.33, d~expt~, = 2.02 g · cm^−3^, d~calc~ = 2.026 g · cm^−3^, Z = 4 and the space group is P2~1~2~1~2~1~. The structure has been solved to an R value of 0.02 for all the 1239 reflections with I > 2σ(I). The sarcosine molecule exists as zwitterion in the structure. The barium ion is found to have 10‐fold coordination with nine oxygens and a chlorine taking part in coordination. All the water oxygens and chlorines take part in hydrogen bonds except carboxyl oxygens.
