Abstract
AbstractSingle crystals of sarcosine cadmium chloride were crystallised from a saturated aqueous solution containing stoichiomeric amounts of sarcosine and cadmium chloride, in 1:1 proportion. The intensity data were collected using a CAD‐4 diffractometer with graphite monochromated MoKα, radiation. The crystal data are as follows: a = 6.916(1) Å, b = 13.855(3) Å, c = 7.981(1) Å, V = 764.1 Å · F.W. = 272.4, dexpt = 2.39 g · cm−3, dcalc = 2.368 g · cm−3, Z = 4 and the space group is P21/n. The structure has been solved to an R value of 0.023 for all the 1323 reflections with I > 2σ(I). The sarcosine molecule exists as zwitterion in the structure. The conformation of the sarcosine molecule is significantly changed due to the complexation of the molecule with cadmium chloride. The cadmium ion is found to have an octahedral coordination with both the oxygens of the carboxyl group of the amino acid and chlorines taking part in it. Since the complex has no water of hydration, only two hydrogen bonds of the types NH ‥ O and NH ‥ Cl are found.
