Abstract

The monoclinic crystal structure of tetrasarcosine potassium iodide dihydrate {or catena-poly[[potassium-tetra-µ-sarcosine-k4O:O';k4O:O] iodide dihydrate]}, {[K(C3H7NO2)4]I·2H2O}n or Sar4·KI·2H2O (space group C2/c), comprises two crystallographically different sarcosine molecules and one water molecule on general positions, and one K+ cation and one I- anion located on twofold axes. The irregular eight-coordinated K+ polyhedra are connected into infinite chains along [001] via sarcosine molecules. This compound is the first sarcosine metal halogenide salt with a 4:1 ratio. A short overview of other sarcosine metal halogenide salts is presented and relationships to similar glycine salts are discussed.
